SCENARIO 2-13
Given below is the stem-and-leaf display representing the amount of detergent used
in gallons (with leaves in 10ths of gallons) in a day by 25 drive-through car wash
operations in Phoenix.

Referring to Scenario 2-13, if a percentage histogram for the detergent data is
constructed, using " 9.0 but less than 10.0 gallons" as the first class, what percentage
of drive-through car wash operations use less than 12 gallons of detergent in a day?
