Question 5 You wish to test the following claim (Ha) at a significance level of a = 0.02. Ho : p = 0.73 Ha : p # 0.73 You obtain a sample of size n = 156 in which there are 106 successful observations. What is the critical value for this test? (Round answer to three decimal places. ) critical value = # What is the test statistic for this sample? (Do not round in between steps. Round only at the end to three decimal places.) test statistic = The test statistic is... O in the critical region O not in the critical region This test statistic leads to a decision to... O reject the null O accept the null O fail to reject the null As such, the final conclusion is that... There is sufficient evidence to warrant rejection of the claim that the population proportion is not equal to 0.73. There is not sufficient evidence to warrant rejection of the claim that the population proportion is not equal to 0.73. The sample data support the claim that the population proportion is not equal to 0.73. There is not sufficient sample evidence to support the claim that the population proportion is not equal to 0.73
