Heights of collegeaged females are normal and centered at about 65 inches, whereas heights of collegeaged males are normal and centered at about 70 inches. Use software to access the student survey data and complete the following tasks.
a. Produce a histogram of heights of all students. Describe its shape.
b. Are there roughly equal numbers of males and females in the data set? If not, which group is larger? c. Separate the data by gender and produce a histogram of heights of female students. Describe its shape.
d. Produce a histogram of heights of male students. Describe its shape. e. To better understand the behavior of the variable height, is it better to study males and females separately, or to combine them?
