The number of successes and the sample size for a simple random sample from a population are given below.
x = 30, n = 50, Ho: p=0.7, Hạ: p#0.7, a = 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.

a. The sample proportion is 0.6.
(Type an integer or a decimal. Do not round.)
b. Is it appropriate to use the one-proportion z-test?
Yes, it is appropriate, because the sample
is
a simple random sample and both np, and n(1 - Po) are 5 or greater.
c. Determine the test statistic, if appropriate. Select the correct choice below and, if necessary, fill in the answer box to complete your answer.
A.
| (Round to two decimal places as needed.)
B. The one-proportion z-test is not appropriate.
