You wish to test the following claim (Ha) at a significance level of a = 0.01. Ho: p = 63.4 Ha : ul # 63.4 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 789 with a mean of M = 62.6 and a standard deviation of SD = 6.9. What is the critical value for this test? (Round to three decimal places.) Critical value = What is the test yatistic for this sample? (Round to three decimal places.) test statistic = | The test statistic is... 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 mean is not equal to 63.4. O There is not sufficient sample evidence to support the claim that the population mean is not equal to 63.4. Question Help: Message instructo
