Instructions: In the next question you will use the data in the table to find the median fit regression line. To begin, you will need to find the sample size and determine the group sizes. Car Weight Miles Per Gallon 2200 33 4400 19 3 3200 26 4700 17 2300 37 2700 32 4100 22 8 3700 26 2500 33 10 3500 28 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
