The number of sue-uses and the sample size for a simple random sample from a population are given below. x=B, I'l =32, H: p= 0.2, Ha: prelim. o:=0.05 a. Determine the sample proportion. h. Decide whether using the one-proportion ztest is appropriate. 1:. If appropriate. use the oneproportion ztest to perfolm the specied hypothesis test.

The sample proportion is 0.25 . {Type an integer or a decimal. Do not round.} b. Is it appropriate to use the oneproportion Ztest'? a? Yes '3' 3' No c. Determine the test statistic, if appropriate. Select the correct choice below and, if necessary, ll in the answer box to complete your answer. tit-VA z: 9.?1 [Round to two decimal places as needed.) {3' B. The oneproportion ztest 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. XA. 17 /2= + (Round to two decimal places as needed.) B. z = 1.64 (Round to two decimal places as needed.) O C. -ZX = (Round to two decimal places as needed.) O D. The one-proportion z-test is not appropriate. What is the conclusion of the hypothesis test? O A. Do not reject Ho; the data do provide sufficient evidence to conclude that p > 0.2. O B. Reject Ho; the data do not provide sufficient evidence to conclude that p > 0.2. C. Do not reject Ho; the data do not provide sufficient evidence to conclude that p > 0.2. O D. Reject Ho; the data do provide sufficient evidence to conclude that p > 0.2
