## Answer to relevant Questions

a. Rejection region. b. Nonrejection region. c. Critical value(s). d. Significance level. e. Construct a graph similar to that in Fig 9.2 on page 350 that depicts your results from parts (a)–(d). f. Identify the hypothesis ...A left-tailed test with α = 0.05. Determine the critical value(s) for a one-mean z-test. For each exercise, draw a graph that illustrates your answer. The P-value for a hypothesis test is 0.083. For each of the following significance levels, decide whether the null hypothesis should be rejected. a. α = 0.05 b. α = 0.10 c. α = 0.06 Two-tailed test: a. z = 3.08 b. z = −2.42 We have given the value obtained for the test statistic, z, in a one-mean z-test. We have also specified whether the test is two tailed, left tailed, or right tailed. Determine ...Each part of this exercise provides a scenario for a hypothesis test for a population mean. Decide whether the z-test is an appropriate method for conducting the hypothesis test. Assume that the population standard deviation ...Post your question
