Question

7. True or False: a. (1) Compared to using ?-0.01, choosing ? 0.001 will make it less likely that a true null b. (1) In a right-tailed test, the null hypothesis is rejected when the value of the test C. (1) If the alternative hypothesis is ? > 50, we have a left-tailed test. hypothesis will be rejected. statistic exceeds the critical value. d. (1) The test statistic for a test that compares the means of two independent samples can be negative. (1) With pooled data, we must have an equal number of observations in each sample group. e. f. (1) The number of data points need for a two-factor with replication ANOVA, where g. (1) A hypothesis test that compares the medians from two groups uses the t distribution h. (1) If every observation in our sample has a value below the benchmark median, then factor A has 4 possible values and factor B has 3 possible values, is 12. to find critical values. the test statistic for the Wilcoxon Signed Rank test is 0.

Explanation / Answer

Solution:-

a) True, the probability rejection of null hypothesis depends upon the value of value of alpha.

b) True, Since in the right tailed test rejection region is on the right side of the tail, hence if the test statistic value exceeds that value then null hypothesis is rejected.

c) False, This is right tailed test.

d) True, the value of test statistics can be negative or positive.
