Answer to Question 1

D

Answer to Question 2

There are times when the mean would still be the preferred measure even if the distribution were skewed. Consider an insurance company that most likely faces a right-skewed distribution of claims. If the company wants to know the most typical claim size, the median is preferred. However, suppose the company wants to know how much money needs to be budgeted to cover claims, then the mean is preferred.
