The number of successes and the sample size for a simple random sample from a population are given below. x=30, n = 50, H₁: p=0.7, H₂: p<0.7, α = 0.10 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.

The one-proportion z-test is not appropriate. Identify the critical value(s), if appropriate. Select the correct choice below and, if necessary, fill in the answer box to complete your answer.
