Multiple Choice: Question #1 A two tailed hypothesis test is being used to evaluate a treatment effect with ( a = .05). if the sample data produce a Z-score of ( z= -2.24), what is the correct decision? A. Reject the null hypothesis and conclude that the treatment has no effect B. Reject the null hypothesis and conclude that the treatment has an effect C. Fail to reject the null Hypothesis and conclude that the treatment has no effect D....

In a two tail hypothesis test the value of one tail is 0.041 and α= 0.01, what statistical decision will you make regarding the null hypothesis you are testing (reject or not reject)?

(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...

Consider the following hypothesis test. H0: μ ≤ 50 Ha: μ > 50 A sample of 60 is used and the population standard deviation is 8. Use the critical value approach to state your conclusion for each of the following sample results. Use α = 0.05. (Round your answers to two decimal places.) (a)x = 52.5 Find the value of the test statistic. State the critical values for the rejection rule. (If the test is one-tailed, enter NONE for the...

Please determine for each of the following whether you REJECT H0 or DO NOT REJECT H0. a. The tails for a two-tailed hypothesis test for the mean are defined by values z = ± 1.69. The test value is z = –1.83. b. The test statistic for a right-tailed hypothesis test for the mean with 99% confidence is z = 1.45. c. The test statistic for a two-tailed hypothesis test for the standard deviation is χ2 = 6.32. The sample...
