a.

Answer to Problem 17E
Nine cities.
Explanation of Solution
Given information:
The line plot shows a sample of prices per gallon of unleaded regular gasoline from
Calculation:
From the line plot, there are nine cities where the price of gasoline is less than
Thus, there are nine cities where the price of gasoline is less than
b.
The representation of conclusion from the study by using
b.

Answer to Problem 17E
Range
Explanation of Solution
Given information:
The line plot shows a sample of prices per gallon of unleaded regular gasoline from
Calculation:
The range is the difference of the largest and the smallest data so:
Range
Range
Thus, the range of prices is equal to the
