Question
The graph portrays the decision criterion for a hypothesis test for a population mean. The null hypothesis is Ho: µ=µ0: The curve
is the normal curve for the test statistic under the assumption that the null hypothesis is true. Use the graph to solve the problem.
A graphical display of the decision criterion follows.
Reject H,
Do not reject H.
