14. What does a p-value NOT tell you? a.) The size of the largest rejection region that would not contain the observed test statisticb.) The probability that the null hypothesis is true and you would observe a test statistic more extreme than the one observedc.) The highest value of for which you cannot reject the null hypothesis based on the datad.) The probability that the null hypothesis is trueAns: d Level: Moderate Section: 3.5 15.

If you are performing a two-tailed test of significance and you find that the area to the left of |tcis .975, what is the p-value? | b Level: Easy Section: 3.5 18. If you are performing a left-tailed significance test and find the area to the left of |tc| is .99, what is the p-value? c Level: Moderate Section: 3.5 19. When should a left-tailed significance test be used? a.) When economic theory suggests the coefficient should be positiveb.) When it allows you to reject the null hypothesis at a lower p-valuec.) When economic theory suggests the coefficient should be negatived.) When you know the true value of 2is positive. Ans: c Level: Moderate Section: 3.5 • • •
