Consider the following situation. a right-tailed test with α = 0.1 Find the appropriate rejection regions. (Round your answers to two decimal places. If the test is one-tailed, enter NONE for the unused region.) z > z < State your conclusion if the observed test statistic was z = 2.17. If appropriate, provide a measure of reliability for your conclusion. a. The null hypothesis is not rejected. b. The null hypothesis is rejected at the 0.1% level. c. The null...
For a two-tailed test at the 0.01 significance level, what is the rejection region when a sample n=25 is drawn from a normal population with unknown standard deviation? Select one: a. Less than -2.797 and greater than 2.797. b. Less than -2.492 and greater than +2.492. c. Less than -2.797 or greater than +2.797. d. None of the suggested answers are correct. e. Less than -2.492 or greater than +2.492.
A one-tailed test is a a. hypothesis test in which rejection region is only in the upper tail of the sampling distribution b. hypothesis test in which rejection region is in both tails of the sampling distribution c. hypothesis test in which rejection region is only in the lower tail of the sampling distribution d. hypothesis test in which rejection region is in one tail of the sampling distribution

(a) For the same data and null hypothesis, is the P-value of a one-tailed test (right or left) larger or smaller than that of a two-tailed test? pick one The P-value for a one-tailed test is smaller because the two-tailed test includes the area in both tails. The P-value for a one-tailed test is larger because the two-tailed test includes the area in only one tail. The P-value for a one-tailed test is larger because the two-tailed test includes the...
In a one-tailed test, the rejection region is located under one tail (left or right) of the corresponding probability distribution, while in a two-tailed test this region is located under both tails.
