c. It should appear in the tail signifying a positive relationship, with .05 in that tail. d. It should appear in the tail signifying a negative relationship, with .05 in that tail. An administrator working in a child guidance center tests the hypothesis that family income will be related to number of treatment sessions attended. Her sample size is large, and her level of significance is .05. How should her critical region appear in her theoretical sampling distribution? a. It should be split between the right and left tails, with .05 appearing in each tail. b. It should be split between the right and left tails, with .025 appearing in each tail. c. It should appear in the tail signifying a positive relationship, with .05 in that tail. d. It should appear in the tail signifying a negative relationship, with .05 in that tail. Slide 15: Here’s the same curve demonstrating the z-score values for 2.5% at each tail. Slide 16: This curve demonstrates a one-tail hypothesis with the critical region representing 5% showing a positive relationship. Slide 17: This curve demonstrates a one-tail hypothesis with the critical region representing 5% showing a negative relationship. Please answer the following quiz questions. Which of the following statements is true about one-tailed tests of significance? a. The critical region is at both ends of the theoretical sampling distribution. b. They increase the chances of reaching the critical region if the results

Question 4: The mode is the most frequently occurring value in a set of data so here the mode is 178 so the answer is e.
7. The data set for this problem can be found through the Pearson Materials in the Student Textbook Resource Access link,
The critical value for significance level α=0.05 for an upper-tailed z-test is given as 1.645.
• Alternative Hypothesis Ha: µ ≥ 50,000, this means the test is a one tailed z test.
D. It would probably see no change in its revenue position as its competitors would raise their prices accordingly.
