Expert Solution
Step 1
The critical region is t > 1.875.
That is, if standardized test statistic is greater than 1.875 then reject the null hypothesis. Otherwise fail to reject the null hypothesis.
a)
t = 1.937
Since 1.937> 1.875, decision is to reject the null hypothesis.
b)
t = 0
Since 0 < 1.875, decision is fail to reject the null hypothesis.
