Week 8 Signature Assignment and Video Response

Part 1: You will be applying what you have learned in this course by gathering data and running a statistical analysis.

To study the relationship between height and the weight of people you know, you need to collect a sample of nine (9) people using a systematic sampling method.
Where and how are you going to collect your sample?
Collect the sample and record the data.
Construct a confidence interval to estimate the mean height and the mean weight. (CLO 1)
Find the sample mean and the sample standard deviation of the height.
Find the sample mean and the sample standard deviation of the weight.
Construct a confidence interval to estimate the mean height.
Construct a confidence interval to estimate the mean weight.
Test a claim that the mean height of the people is not equal to 64 inches using the p-value method or the traditional method. (CLO 2)

State H0 and H1.
Find the p-value or critical value(s).
Draw a conclusion.
Find the correlation coefficient between the height and the weight.
Construct the equation of the regression line and use it to predict the weight of a person who is 68 inches tall. (CLO 3)
Write one to two paragraphs about what you have learned from this process.
When you read, see, or hear a statistic in the future, what skills will you apply to know whether you can trust the result?

Where and how the sample will be collected is clearly and accurately described. The data for all nine people is recorded.

A confidence interval to calculate the mean height and weight was correctly calculated with all necessary work being shown

Accurately stated H0 and H1 and correctly calculated the p-value with all necessary work being shown. Thoroughly described the conclusion drawn, and what the statistical analysis means.

Accurately found the correlation coefficient between the height and the weight. Correctly constructed the equation of the regression line, showed all work, and used it to predict the weight of a person who is 68 inches tall.

Wrote a paragraph or two that clearly described what was learned, and how the student can critically think about the use of statistics in a real-world setting.

   a. Where and how are you going to collect your sample?
   To get the data about the weight and height of the people I know, the best place would be my friends in class. Their acceptability will be higher since they either already know the reason for the data collection or I can easily convince them to give their | GET AN EXPERT FOR YOUR ASSIGNMENT | of my classmates and request them to be part of my data collection process. Those who turn down the request will be replaced from the bigger sample size which is the entire class. Thereafter, using a tape measure and a weighing scale from the laboratory, I will record their individual heights and…
