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? Weight Height 150lbs 68 inches 135lbs 67 inches 135lbs 64inches 130lbs 69inches 165lbs 73 inches 156lbs 71 inches 116lbs 65inches 120lbs  63inches 175lbs 72inches

We are interested in examining the relationship between the number of calories people consume and weight. We randomly selected 200 people and presented the data with explanatory (x) variable being the calories consumed and the response (y) variable being their weight. Regression analysis will be good for this problem because it helps us find trends in data and quantify the results. It can also help us make predictions about data. So as long as the requirements are met for inference...
