You wish to test the following claim (Ha) at a significance level of a = 0.02. Ho:= 68.9 Ha: μ > 68.9 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 11 with mean M = 75.8 and a standard deviation of SD = 5.7. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = The p-value is... O less than (or equal to) a O greater than a This test statistic leads to a decision to... O reject the null 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 mean is greater than 68.9. O There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 68.9. O The sample data support the claim that the population mean is greater than 68.9. O There is not sufficient sample evidence to support the claim that the population mean is greater than 68.9.
