Question
7.28 Fuel efficiency of manual and automatic cars, part 1.
each year the US environmental protection agency (EPA) releases fuel economy data on cars manufactured in that year. below are summary statistics on fuel efficacy (in miles/gallon) from random samples of cars with manual and automatic transmissions. do these data provide strong evidence of a difference between the average fuel efficiency of cars with manual and automatic transmissions in terms of their average city mileage? assume that conditions for inference are satisfied.
Automatic Mean = 16.12
Automatic SD = 3.58
n = 26
Manual mean = 19.85
manual SD = 4.51
n = 26
