The Majoring in Money study by Sallie Mae from December 2015 showed that most college students manage their credit cards in a reasonable way. It showed that almost two-thirds of students pay their credit card balance in full every month and 26% of students who own credit cards make partial payments that exceed the minimum amount due. You are curious to find out if credit card payment behavior of students has changed since 2015 and collect data from a random sample of 360 students. You find that 72 students are making partial payments on their credit cards that exceed the minimum amount due. Using α = 0.01, answer the following questions:

a. Does this sample provide support for the hypothesis that the proportion of students who make partial payments that exceed the minimum amount has decreased since 2015?

b. Determine the p-value for this test.
