Answer to Question 1

B

Answer to Question 2

Answers will vary. An example of a right skewed distribution might be the ages of all members (e.g. athletes, coaches) of a gymnastics team. A majority of the members would be quite young, however the older athletes and coaches will skew the distribution to the right.
