The table provides summary statistics on highway fuel economy of cars manufactured in a certain year.

Hwy MPG
Automatic Manual
Mean 22.92 28.87
SD 5.28 5.02
n 26 26

Use these statistics to calculate a 98% confidence interval for the difference between average highway mileage of manual and automatic cars, and interpret this interval in the context of the data. (Round your answers to two decimal places.)

We are 98% confident that on the highway cars with manual transmissions get on average (?) to (?) MPG more than cars with automatic transmissions.

Fuel Efficiency of Manual and Automatic Cars Each year the US Environmental Protection Agency (EPA) releases fuel economy data on cars manufactured in that year. Below are summary statistics on fuel efficiency (in miles/gallon) from random samples of cars with manual and automatic transmissions manufactured in 2012. 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...
