1. A college has been given a sizable grant: enough to build either a new library or gymnasium. But, as there is only money enough to build one facility, the president wants to ask students which one they feel is in greater need of renovation. Suppose there are 500 male students and 400 female students in the school.

a) What is the population under study? (3 points)

b) The president wants to randomly ask 50% of the students. How many students would this be? (3 points)

c) Now the president wants to keep the correct proportion of female to male students in the sample. What type of sampling method would be used here? How many girls would be selected? (6 points) d) What is the level of measurement for the students' response? (3 points)
