1. What is the sample size?
2. How many cars should be in the Low, Medium, and High groups?
(Hint: Divide the sample size by 3. If there is a remainder, add
those to the group or groups that would make the distribution
symmetric.)
Low: There are
cars in this set.
Medium: There are
cars in this set.
High: There are
cars in this set.
