Chapter 12.2, Problem 15P
The amount of gasoline that 80 drivers bought to fill their cars' gas tanks is shown.
How many drivers bought 9 gallons or less?
Expert Solution & Answer
To determine
Find the number of drivers that bought 9 gallons or less.
Answer to Problem 15P
22
Explanation of Solution
Given:
The amount of gasoline that 80 drivers bought to fill their cars’ gas tanks is :
Calculation:
Since the number of drivers is represented on y-axis and the number of gallons is represented on the x-axis.So, the first 3 intervals represent 9 or less number of gallons.
The number of drivers that bought 0.1-3 gallons of gasoline = 2
The number of drivers that bought 3.1-6 gallons of gasoline = 8
The number of drivers that bought 6.1-9 gallons of gasoline = 12
Hence, total number of drivers that bought 9 or less gallons of gasoline = 2+8+12 = 22
