You wish to test the following claim (Ha) at a significance level of a = 0.10. How. = 66.8 Ham > 66.8 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size 'n. = 22 with mean M = 70.4 and a standard deviation of SD = 18.6. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = [3 What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = C] The p-value is... x O less than (or equal to) a Q greater than or This test statistic leads to a decision to... C] reject the null [I] accept the null D fail to reject the null As such, the final conclusion is that... C] There is sufficient evidence to warrant rejection of the claim that the population mean is greater than 66.3. [:1 There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 66.8. C] The sample data support the claim that the population mean is greater than 66.8. Q There is not sufficient sample evidence to support the claim that the population mean is greater than 66.8
