We have given the number of successes and the sample size for a simple random sample from a population. In each case, do the following.

a. Determine the sample proportion.

b. Decide whether using the one-proportion z-test is appropriate.

c. If appropriate, use the one-proportion z-test to perform the specified hypothesis test.
