1. In a test of hypothesis, if the p-value of the test statistic 0.06 when a) Reject the null hypothesis b) Do not reject the null hypothesis e You cannot decide until you also compare the value of the test stati d) Do nothing and review the work because this should never occur critical value 21 If a Minitab output shows p-value-0.000, then which interpretation is correct? a) The p-value is exactly zero The p-value is less than 0.001 b) c) d) The p-value is greater than 0.001 The p-value is less than zero 3. Suppose that a test of hypothesis results in rejection of the null hypothesis when using .05. Then if instead you use =0.01, you would a) b) c) d) Still reject the null hypothesis Not reject the null hypothesis Rerun the test because the value of the test statistic would change Be unable to decide without also knowing the p-value of the test statistic 4. The purpose of an ANOVA test is to determine whether or not a) b) c) d) Multiple populations have equal variances Multiple populations have equal means Multiple populations have equal sizes Multiple populations have equal standard deviations Js. The test statistic that is used for the ANOVA test is 5. a) X2 b) t c) F 6. When using ANOVA, a sum-of-squares calculation divided by its associated degrees of f called a a) Confidence interval b) Significance level c) Mean square d) p-value Page 1 of 8Explanation / Answer
