Question 7 You wish to test the following claim (Ha) at a significance level of a = 0.05. Ho:p = 0.79 Ha: p > 0.79 You obtain a sample of size n = 128 in which there are 113 successful observations. What is the critical value for this test? (Round to three decimal places.) Critical value = What is the test statistic for this sample? (Round to three decimal places.) Test statistic = The test statistic is... O in the critical region not in the critical region This test statistic leads to a decision to... O reject the null O fail to reject the null As such, the final conclusion is that... . O The sample data support the claim that the population proportion is greater than 0.79. There is not sufficient sample evidence to support the claim that the population proportion is greater than 0.79
