1y answered Question 3 GO You wish to test the following claim (Ha) at a significance level of a = 0.005. Ho: u = 53.9 Ha: M # 53.9 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 87 with a mean of M = 54.8 and a standard deviation of SD = 8.4. 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... 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... The sample data support the claim that the population mean is not equal to 53.9. There is not sufficient sample evidence to support the claim that the population mean is not equal to 53.9
