Test H0 : p = 0.75 vs Ha : p ≠ 0.75 using the sample results p^ = 0.69 with n = 120
Use the normal distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from a random sample and use a 5% significance level. Test H0 : p=0.75 vs Ha : p≠0.75 using the sample results p^=0.69 with n=118 Round your answer for the test statistic to two decimal places, and your answer for the p-value to three decimal places. test statistic = p-value = Conclusion:
