Answer to Question 1

A

Answer to Question 2

IF THE SAMPLE SIZE IS VERY SMALL, A RELATIONSHIP THAT EXISTS IN THE POPULATION MAY GO UNDETECTED (NOT STATISTICALLY SIGNIFICANT). IF THE SAMPLE SIZE IS VERY LARGE, A RELATIONSHIP THAT IS NOT VERY STRONG IN THE POPULATION MAY BE DETECTED (STATISTICALLY SIGNIFICANT).
