Thenoncritical/do not rejectregion is a range of test statistic values which indicates that the difference between the postulated value for the parameter (mean, proportion, etc.) and the corresponding point estimate (from the sample) value is probably due to chance. Thus, the null hypothesis 0H0 should not be rejected.

Consider the following:

0H0: =150=150

1H1: >150>150

Is the hypothesis test left-tailed, right-tailed, or two-tailed? Justify your conclusion.
