Explanation / Answer

The rejection region as defined from the graph is:

Rejection region is -

The standardized test statistic values which are greater than or equal to 28.8690

We reject Ho if the standardized test statistic is in the rejection region.

That means that:

we reject Ho if the standardized test statistic is greater than or equal to 28.8690

For the cases

(a), (b), (c), (d) -

The standardized test statistics are -> 12.221, 0, 1.321, 28.840

All these standardized test statistics are less than 28.8690

So, none of these standardized test statistics are in the rejection region.

So, we fail to reject the null hypothesis for all the 4 cases.

So, the answer for all the 4 cases is:

Do not reject the null hypothesis because the standardized test statistic is not in the rejection region.
