The following hypotheses are given. H0 : π ≤ 0.75 H1 : π > 0.75 A sample of 130 observations revealed that p = 0.89. At the 0.10 significance level, can the null hypothesis be rejected?

a. State the decision rule. (Round your answer to 2 decimal places.) Reject H0 if z >

b. Compute the value of the test statistic. (Round your answer to 2 decimal places.) Value of the test statistic

c. What is your decision regarding the null hypothesis? H0.
