The critical value of a two-sided t-test computed from a large sample A) is 1.64 if the significance level of the test is 5%. B) cannot be calculated unless you know the degrees of freedom. C) is 1.96 if the significance level of the test is 5%.

PROBLEM SET 1 For the first three answer true or false and explain your answer. A picture is often helpful. 1. Suppose the significance level of a hypothesis test is α=0.05. If the p-value of the test statistic is p-value = 0.07, then the null hypothesis (H 0) should be rejected. False. We reject the null hypothesis when the p-value is less ...
