You wish to test the following claim (Ha) at a significance level of a = 0.05. Ho: u = 82.3 Ha: H > 82.3 (Claim) You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 93 with mean a = 89.6 and a standard deviation of s = 17.2. a.) What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = b. ) What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = (use Excel) c.) The p-value is... greater than a O less than (or equal to) a d. ) This test statistic leads to a decision to... O accept the null hypothesis O reject the null hypothesis O fail to reject the null hypothesis e. ) As such, the final conclusion is that... There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 82.3. O There is not sufficient sample evidence to support the claim that the population mean is greater than 82.3. There is sufficient evidence to warrant rejection of the claim that the population mean is greater than 82.3. The sample data support the claim that the population mean is greater than 82.3
