A. 2.58B. 1.65C. 2.33 D. 1.962) The area of rejection, on a bell shaped curve, defines the location of all those values that are A. so small or so large that the probability of their occurrence under a true null hypothesis is rather slim B. so small or so large that the probability of their occurrence under a true null hypothesis is to be expectedC. within the selected confidence interval for the testD. so small or so large that the probability of their occurrence under a false null hypothesis is rather remote3) A hypothesis test that involves a small sample requires that we make the following assumption thatA. the population is normally distributedB. the region of acceptance will be wider than for large samplesC. a larger computed value of t will be needed to reject the null hypothesisD. the confidence interval will be wider than for large samples4) A statistician was setting up a hypothesis test with a level of significance dictated by upper management. However, she was concerned that the test she wished to perform might have unacceptable large possibilities of Type II error, . Which of the following would solve this problem? A. Convince upper management to reduce the level of significance of the test.B. Convince upper management to use a smaller p-value.C. Conv
