Question

6. [3] A hypothesis test result is found to be statistically significant, but not of practical importance. Which of the explanations below best reflect the meaning of the statement above? While there is enough evidence to reject the null hypothesis the effect size is so small as to render a. policy changes due to the result unnecessary. b. There was not enough evidence to reject the null hypothesis and thus we will continue to assume the null hypothesis is correct. The null hypothesis is not rejected because the p-value was not of practical importance. The null hypothesis is not rejected because the p-value was not low enough. c. d. Your response is:_

Explanation / Answer

Since the result was statistically significant, it means that there was enough evidence to reject the null hypothesis but the effect size was too small to consider it practically significant.

Option A is correct.
