Consider the following sample data: 153, 178, 203, 410, 310, 231, 190, and 225. Compute the mean and median. Is the distribution of these numbers skewed to the right, skewed to the left or symmetric? Why?
 
  What will be an ideal response?

Question 2

Answer to Question 1

Mean = 237.5, median = (203 + 225)/2 = 214. Since mean > median, the distribution of these numbers is skewed to the right.

Answer to Question 2

P(X > 1 ) = 0.005
