The graph to the right portrays the decision criterion for a hypothesis test for a population mean p. The null hypothesis for the test is Ho: p = po. The curve in the graph is the Reject Do not reject Ho normal curve for the test statistic under the assumption that the null hypothesis is true. Complete parts (a) through (?) below. Ho I -1.2820 a. Determine the rejection region. A. z> - 1.282 O B. zs - 1.282 O C. z> 1.282 O D. zS - 1.282 or zz 1.282 b. Determine the nonrejection region. A zS 1.282 O B. - 1.282 - 1.282 O D. - 1.282 SzS 1.282 c.
