Suppose that two population proportions are being compared to test whether there is any difference between them. Assume that the test statistic has been calculated to be z = 2.21. Find the p-value for this situation.

A) p-value = 0.0136
B) p-value = 0.4864
C) p-value = 0.0272
D) p-value = 0.9728

Question 2

When customers come to a bank, there are three primary locations they may select to go to: teller, loan officer, or escrow department. Based on past experience, the following probability distribution applies:

Location Probability
Teller 0.60
Loan Officer 0.30
Escrow 0.10

Seventy percent of customers are males. Thus, the probability that the next customer to enter the bank is a male who goes to the teller is 1.30.
