Answer:

A. Reject H0 because the​ P-value is less than or equal to α.

Step-by-step explanation:

Decision:

If the pvalue of the test is less than the significance level, we reject the null hypothesis H0.

Otherwise, we fail to reject the null hypothesis H0.

In this question:

Significance level: 0.01

P-value: 0.0087

0.0087 < 0.01, so we reject H0.

The correct answer is given by option A.
