## Question:

The accompanying data set contains three variables, x_{1}, x_{2}, and x_{3}.

a. Bin the values of x_{1} into three equal-size groups. Label the groups with numbers 1 (lowest values) to 3 (highest values). How many observations are assigned to group 1?

b. Bin the values of x_{2} into three equal-interval groups. Label the groups with numbers 1 (lowest values) to 3 (highest values). How many observations are assigned to group 2?

c. Bin the values of x_{3} into the following three groups: < 50,000, between 50,000 and 100,000, and > 100,000. Label the groups with numbers 1 (lowest values) to 3 (highest values). How many observations are assigned to group 1?
