A salesman kept track of the gas mileage for his car over a 25-week span. The mileages (miles per gallon rounded to the nearest whole number) were: 23, 27, 27, 28, 25, 26, 25, 29, 26, 27, 24, 26, 26, 24, 27, 25, 28, 25, 26, 25, 29, 26, 27, 24, 26. What are the mean, the median, and the mode?

Step-by-step explanation:

23, 27, 27, 28, 25, 26, 25, 29, 26, 27, 24, 26, 26, 24, 27, 25, 28, 25, 26, 25, 29, 26, 27, 24, 26

Arranging in ascending order;

23, 24, 24, 24, 25, 25,  25, 25, 25, 26, 26, 26, 26, 26, 26, 26, 27, 27, 27, 27, 27, 28, 28,  29, 29

Mean = Sum of mileage / Number of millage

Number of mileage = 25

Sum of mileage = 651

Mean = 651 / 25 = 26.04

Median = Middle Number (13th number) = 26

Mode (Highest occurring) = 26 (7 times)
