A medical school claims that more than 32% of its students plan to go into general practice. It is found that among a random sample of 130 students, 46 of them plan to go into general practice.

a. Formulate the hypotheses to test the medical school's claim.

b. Test these hypotheses and draw a conclusion about the claim. Use an alpha level of 0.05 (show your work and state your conclusion)

c. Find the p-value for the test of the schools claim. Does this p-value support your conclusion ? Why or why not?
