Statistics Homework
Introduction to Statistics homework: Statistics is defined as a process of analysis and organize the data. We learn about mean, median, mode in statistics. Mean is same as average in arithmetic. Median is the midvalue of the data. Mode is the value of the data that appears most number of times. Statistics deals with mean, deviation, variance and standard deviation. The process of finding the mean deviation about median for a continuous frequency distribution is similar as we did for mean deviation about the mean plastic card for sale. It is a technology to collect, manage and analyze data. In this article, Basic functions and homework problems on statistics are given. Statistics Functions and Examples: In statistics the mean which has the same as average in arithmetic. In statistics mean is a set of data which can be dividing the sum of all the observations by the total number of observations in the data. Sum of observations Mean = ------------------------------------ Number of observations The statistic is called sample mean and used in simple random sampling. The mean of deviation has discrete frequency distribution and Continuous frequency distribution FDD-LTE module. The mean deviation and median for a continuous frequency distribution is similar as for mean deviation about the mean. Median is found by arranging the data first and using the formula If n is even, Median = '1/2[ n/2 "th item value"+(n/2+1) "th item value"]' If n is odd, Median = '1/2 (n+1)'th item value Variance: In statistics the variance s2 of a random variable X and of its distribution are the theoretical counter parts of the variance s2 of a frequency distribution. In a given data set of the variance can be determined by the sum of square of each data. Here variance is represented by Var (X). The formula to solve the variance for continuous and discrete random variable distributions can be shown. In statistics variance is the term that explains how average values of the data set vary from the measured data. s2 = ?(X - M) 2 / N S2 = ?(X - M) 2 / N Standard Deviation: It is an arithmetical figure of spread and variability Ex 1 : Choose the correct for normal frequency distribution. A. mean is same as the standard deviation B. mean is same as the mode C. mode is same as the median D. mean is the same as the median Ans: D Ex 2 : Choose the correct variable for confounding. A. exercise B. mean C. deviation D. Occupation Ans : A Ex 3: The weights of 8 people in kilograms are 60, 58, 55, 72, 68, 32, 71, and 52. Find the arithmetic mean of the weights. Sol : sum of total number Mean = ------------------------------ Total number 60 + 58 + 55 + 72 + 68 + 32 + 71 + 52 = ----------------------------------------------------------- 8 468 = ------- 8 = 58.5 Ex 4: Find the median of 29, 11, 30, 18, 24, and 14. Sol : Arrange the data in ascending order as 11, 14, 18, 30, 24, and 29 RO RMT. N = 6 Since n is even, Median = '1/2[ n/2 "th item value"+(n/2+1) "th item value"]' = '1/2' [6/2th item value + (6/2 + 1)th item value] = '1/2' [3rd item value + 4th item value] = '1/2' [18 + 30] = '1/2' * 48 = 24 Ex 5: Find the mode of 30, 75, 80, 75, and 55. Sol : 75 are repeated twice. Mode = 75 Ex 6: Find the Variance of (2, 4, 3, 6, and 5). Sol: First find the mean Mean = '(2+3+4+6+5)/5 = 20/5=4' (X-M) = (2-4)= -2, (3-4)= -1, (4-4)=0, (6-4) =2, (5-4) =1 Then we can find the squares of a numbers. (X-M)2 = (-2)2 = 4, (-1) 2 = 1 , 02 = 0, 22 = 4 , 12 = 1 'sum(X-M)^2= 4+1+0+4+1=10' Number of elements = 5 , so N= 5-1 = 4 '(sum(X-M)^2)/N = 10/4=2.5' Here we can add the all numbers and divided by total count of numbers. = (4 + 16 + 9 + 36 + 25) / 5 = 90 / 5 = 18 Ex 7: Find the Standard deviation of 7, 5, 10, 8, 3, and 9. Sol: Step 1: Calculate the mean and deviation. X = 7, 5, 10, 8, 3, and 9 M = (7 + 5 + 10 + 8 + 3 + 9) / 6 = 42 / 6 = 7 Step 2: Find the sum of (X - M) 2 0 + 4 + 9 + 1 + 4 = 18 Step 3: N = 6, the total number of values. Find N - 1. 6 - 1 = 5 Step 4: Locate Standard Deviation by the method. v18 / v5 = 4.242 / 2.236 = 1.89 Homework practice problems: 1. Choose the correct for statistics is outliers. A. mode B. range C. deviation D. median Ans : B 2. Find the arithmetic mean of the weights of 8 people in kilograms is 61, 60, 58, 71, 69, 38, 77, and 51. Sol : 60.625 3.

Antenna Breakdown For The Printed Circuit Board Hobbyist
Depending on the printed circuit board (PCB) the options you have for antennas are going to be varied. Each antenna will have its own unique purpose and the circuit board hobbyist will need to understand these antennas in an effort to be successful. When you are looking to hook up your antenna, it will be important that you connect it to the feed line of your PCB. PCB Trace This is about as basic as you can get for these antennas. These are fairly simple to tune and while they don't exceed performance in things like repeatability, cost, size and even performance, they are going to be a reliable choice that can work in most cases. Whip Antenna Sometimes called the ducky antenna, this is a larger and more effective antenna. They will usually come with an output frequency that has been pre tuned, but you will be able to get a fairly good performance out of them Fruit Milk drink. The only actual issue most people have with them is that they are going to be larger than many of the other PCB antennas you will have available. Wired Monopole Antenna If you are trying to cut down costs, you can use a wire antenna. These are typically frowned upon because they can vary a lot based on location and surroundings. Even the shape of these antennas can affect their performance. Under the best conditions, the wire antenna might be able to reach between 40 - 50 feet Phone battery cases suppliers. Chip Antenna Chip antennas can be a mixed bag Engineered Marble. Some hobbyists love them, but the majority usually does not. What we find with these antennas is that they are very difficult to tune, yet can be detuned without too much difficulty. These antennas will usually work better in cases where you don't have a long distance that you will be looking to transmit. No matter what the style of antenna you are using, it is important that you understand that on your PCB, the antenna portion is going to become very sensitive, especially when copper is added to this area. In some of the advanced choices you have for circuits, you will need to pay close attention to the etching and take into account that this will change the antenna significantly and you may need to accommodate that. One important thing to look at when you are dealing with these antennas is that you are going to need to calibrate the NA and solder your SMA connector to end up with the best operation possible. Keep in mind that all the items that surround the antenna will have an impact on the actual performance of the unit. This includes connectors, batteries, case, wires and even your hands. Make sure that you keep this in mind when you are trying to problem solve any issues that may arise with these antennas.  Order by www.gz-sanitaryware.com/
How We Take Actions to Control Construction Wastes
Construction waste is entirely possible to be recycled by jaw crusher from China. Scrap steel, scrap steel and other scrap metal materials can be processed and directly reused or recycled. So the demand for jaw crusher from China in the construction market has been increased since 2013. Machinery companies will take more efforts to develop and research new type jaw crusher to meet the need of different consumers. With the progress of accelerated urbanization construction, the construction waste has been became a problem that impede city development.

As the main equipment processing construction waste, the jaw crusher from China made great contribution to the construction industry. For the waste concrete, people can use jaw crusher from China as the coarse crushing step, the processed construction waste can be used to be the base of road as well as other building materials such as floor tile, wallboard and concrete materials cup sealing machine.

cheap Toms Shoes

2013年7月18日
Rising junior Ellen Barker is living out the experience of a lifetime this week as she travels with employees of TOMS Shoes to Nicaragua for a TOMS Giving trip.
As president of HPU’s TOMS Campus Chapter, Barker was hand-selected for the giving trip due to her dedication to the chapter, its growth and high level of involvement on campus.
From June 23-28, she will travel to schools throughout the Central American country to distribute shoes to children in need, thereby living out the TOMS company motto of “Buy a pair, give a pair.”
“I’m so excited,” said Barker just before she left. “I’ll be the only non-TOMS employee on the trip, and I can’t wait to meet them and get to know these people who run such an amazing organization. But mostly, I can’t wait see the look on the children’s faces when I hand them a pair of shoes.”
In addition to the distribution, the 11-person team will focus on the culture of Nicaragua and have reflection moments to ask question, note their favorite moment from the day or what they’ve learned.
“I’m going to keep a journal on the trip because I know that I will be a changed person with a new perspective by the time it ends,” she says. “This is one of the most amazing opportunities I’ve ever received.”
Stay tuned to cheap Toms Shoes for a reaction post from Barker when she returns from her trip.
Background:
Barker bought her first pair of TOMS Shoes when she was in high school because she valued the company’s “One for One” motto: for every pair of shoes it sells, the company donates a pair to a child in need. When she came to High Point University, she found a thriving TOMS campus chapter that had landed a spot on the “Top 10 Toms Events of the Year” for its awareness week. She immediately signed up to become a member and be involved at HPU.
Each year, the group hosts several events to spread the TOMS message of giving to their peers. This includes One Day Without Shoes, where hundreds of students pledge to go barefoot to raise awareness about the millions of children in developing countries that have to grow up barefoot. After the events caught the attention of TOMS, they contacted Barker for a Skype interview and told her she had been selected as one of four campus chapter presidents in the country to embark on a TOMS Giving trip.
“I have to thank all of the HPU administration who are so supportive of our club,” Barker says. “They’ve made it possible for us to organize our events, borrow equipment and make connections. HPU sets us up for success, and for that I am grateful.”
In addition to the fulfillment that the HPU TOMS campus chapter brings Barker, she also knows this opportunity is important to her studies and future career.
“TOMS is a for-profit, and I really want to be in the business world someday,” she says. “TOMS is the ideal company that I want to work for – one that is unique, progressive and full of youth and innovation. It’s grown so much so quickly. I just love the business culture there, which is different from what people think of regarding accountants. I’m very social, but I like the detail-oriented nature of accounting. Working at TOMS is basically my dream job.”http://www.zerowastenetwork.org/toms-shoes.html
