## Answer to relevant Questions

A left-tailed test with α = 0.01. Determine the critical value(s) for a one-mean z-test. For each exercise, draw a graph that illustrates your answer. Explain how the P-value is obtained for a one-mean z-test in case the hypothesis test is a. Left tailed. b. Right tailed. c. Two tailed. In each part, we have given the P-value for a hypothesis test. For each case, refer to Table 9.8 to determine the strength of the evidence against the null hypothesis. a. P = 0.184 b. P = 0.086 c. P = 0.001 d. P = 0.012 Consider a one-mean z-test. Denote z0 as the observed value of the test statistic z. If the test is right tailed, then the P-value can be expressed as P(z ≥ z0). Determine the corresponding expression for the P-value if ...Iron is essential to most life forms and to normal human physiology.
