A consumer's group checked the gasoline mileage (to the nearest milr per gallon) on 25 different cars. The following gives a summary of the findings.
Miles per gallon Frequency
less than 15 2
over 40 1
total cars =25
Which of the following quantities can be obtained from the table?
1. The number of cars that got over 30 miles per gallon.
2. The number of cars that got less than 10 miles per gallon.
3. The number of cars that got 30 miles per gallon.
4. The number of cars that got 20-30 miles per gallon.
Ok if you look at the Interval of 21-30 and 31-40 it is 9 which would give you 1 as the answer. Is this right, thanks for looking at this long problem.
