The graph to the right portrays the decision criterion for a hypothesis test for a population mean u. The null hypothesis for the test is Ho: u = Ho. The curve in the graph is the normal curve for the test statistic under the assumption that the null hypothesis is true. Complete parts (a) through (f) below.
