You wish to test the following claim (H1) at a significance level of a = 0.04. Ho:µ = 70.8 H1:µ > 70.8 You believe the population is approximately normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 24 with a mean of = 72.4 and a standard deviation of s = 7.2. Should you use z or t to find a critical region? Select an answer What is the critical value for this test? (Report answer accurate to three decimal places.) critical value = What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = The test statistic is... O not in the critical region O in the critical region This test statistic leads to a decision to... fail to reject the null O reject the null O accept the null As such, the final conclusion is that... O There is sufficient evidence to warrant rejection of the claim that the population mean is greater than 70.8. O There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 70.8. O The sample data support the claim that the population mean is greater than 70.8. O There is not sufficient sample evidence to support the claim that the population mean is greater than 70.8.
