Solved: Group Project: The class should be divided into
Chapter 9, Problem 8.76(choose chapter or problem)
Group Project: The class should be divided into groups of four people. The four students in each group should go to the college gym or a local fitness center. The students should ask each person who comes through the door his or her height in inches. Each group will then divide the height data by gender and work together to answer the following questions.
(a) Construct a normal quantile-quantile plot of the data. Based on the plot, do the data appear to follow a normal distribution?
(b) Use the estimated sample variance as the true variance for each gender. Assume that the population mean height for male students is actually three inches larger than that of female students. What is the probability that the average height of the male students will be 4 inches larger than that of the female students in your sample?
(c) What factors could render these results misleading?
