Question 16 For these examples, use the T-Test, for when population standard deviation is unknown. You wish to test the following daim (Ha) at a significance level of or = 0.10. Ho:u = 86.3 Ha: p > 86.3 You obtain a sample of size n = 766 with mean I = 87.3 and a standard deviation of $ = 10.2. a. What is the test statistic for this sample? test statistic = Round to 3 decimal places b. What is the p-value for this sample? p-value = Use Technology Round to 4 decimal places. c. The p-value is... O less than (or equal to) or O greater than or d. This test statistic leads to a decision to... O reject the null O accept the null O fail to reject the null e. 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 86.3. O There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 86.3. O The sample data support the daim that the population mean is greater than 86.3. O There is not sufficient sample evidence to support the claim that the population mean is greater than 86.3
