HELPPPP The following data set represents the highway fuel efficiency in miles per gallon (mpg) of randomly selected cars from two car companies.
Car Company A: 35, 28, 35, 30, 31, 38, 35, 30
Car Company B: 29, 33, 36, 27, 34, 34, 34, 25
Which of the following statements is true?
Based on the provided data set, it is true that the average highway fuel efficiency of cars from Car Company A is higher than that of cars from Car Company B.
To calculate the average fuel efficiency for each company, we add up all the MPG values and divide by the total number of values:
For Car Company A:
(35 + 28 + 35 + 30 + 31 + 38 + 35 + 30) / 8 = 32.375
For Car Company B:
(29 + 33 + 36 + 27 + 34 + 34 + 34 + 25) / 8 = 31.5
Therefore, the average fuel efficiency of cars from Car Company A is 32.375 mpg, which is higher than the average fuel efficiency of cars from Car Company B, which is 31.5 mpg.
