Q1) One-Sample t-Test (11 points total)
I am shopping for a new sedan and would like to get one with excellent miles per gallon (MPG). I heard that Japanese cars tend to be more fuel efficient than American cars, so I collected MPG data on a random sample of 15 Japanese 4-cylinder sedan models (listed in the table below) to be compared to the American car statistics. I would like to see if there is a significant difference, in either direction, between Japanese sedans and American sedans. The US Environmental Protection Agency reported that the average MPG for American sedans in 2017 is μ = 31. I set the significance level at α = .10 for a two-tailed hypothesis test.
