1. For a random sample of 100 undergraduates, suppose the mean and standard deviation on the SAT math score is equal 508 and 100, respectively. Conduct a significance test to evaluate whether or not the mean score is equal to 500 at the 5% significance level. What would you conclude? A. We reject that the sample mean is equal to 500 B. We fail to reject that the sample mean is equal to 500 C. We reject that the population mean is equal to 500 D. We fail to reject that the population mean is equal to 500 2. For a random sample of 100 undergraduates, suppose the mean and standard deviation on the SAT math score is equal 508 and 100, respectively. Refer to your previous answer. Suppose the true population mean was actually 540. What was incorrect about the conclusion of the previous hypothesis test? A. We rejected the true null B. We calculated the incorrect value of the test statistic C. We failed to reject a false null D. We chose an incorrect significance level
