Question

. Suppose you check the bottom of 61 desks in a lecture hall for gum, and 25 of these desks did not have gum. Let pi denote the proportion of all desks on campus that do not have gum on the bottom. a. Construct a 95% confidence interval for the true population parameter pi. Assume sample size is large enough to use the simplified formula (i.e. no z* should be in your equation). Include an interpretation of your interval. b. What are the general properties of the sampling distribution of P?
