The administration at State University wants to estimate the incoming freshman class’s interest in a computer science major. Because it does not have the fi nancial resources to survey all 5000 freshmen, the administration surveys a random sample of 500. It fi nds that 100 students report they are interested in such a major.

a. Calculate the margin of error in this survey.

b. What is the best estimate of the number of freshmen who would be interested in majoring in computer science?
