Question:

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 histogram for each gender of the data. Based on these plots, 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 3 inches more than that of female students. What is the probability that the average height of the male students will be 4 inches more than that of the female students in your sample?
(c) What factors could render these results misleading?
