Question: Statisticians often need to know the shape of a population to make inferences. Suppose that you are asked to specify the shape of the population of weights of all college students.
a. Sketch a graph of what you think the weights of all college students would look like.
b. The following data give the weights (in pounds) of a random sample of 44 college students (F and M indicate female and male, respectively)
i. Construct a stem-and-leaf display for these data.
ii. Can you explain why these data appear the way they do?
c. Now sketch a new graph of what you think the weights of all college students look like. Is this similar to your sketch in part a?
