For a one-tailed hypothesis test where you reject H0 only in the lower tail, the critical value is - 1.3253. What is the statistical decision if tSTAT = - 1.06?

What is the statistical decision?

A. Since the tSTAT value is less than the critical value, reject H0.

B. Since the tSTAT value is less than the critical value, do not reject H0.

C. Since the tSTAT value is greater than or equal to the critical value, do not reject H0.

D. Since the tSTAT value is greater than or equal to the critical value, reject H0.

Option C

Step-by-step explanation:

Given that for a one-tailed hypothesis test where you reject H0 only in the lower tail, the critical value is - 1.3253

Test statistic = - 1.06

Because it is a one tailed test, we must have

test statistic to be less than the critical value, to reject null hypothesis.

Here we have test statistic - 1.06>-1.3253

So we accept null hypothesis.

Option a, b and d are incorrect.

The correct answer is

C. Since the tSTAT value is greater than or equal to the critical value, do not reject H0.
