I am shopping for a new mid-size SUV 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 10 Japanese mid-size SUV models (listed in the table below) to be compared to the American mid-size SUV statistics. I would like to see if there is a significant difference, in either direction, between Japanese mid-size SUVs and American mid-size SUVs. The US Environmental Protection Agency reported that the average MPG for American mid-size SUVs in 2020 is μ = 28. I set the significance level at a = .10 for a two-tailed hypothesis test. Hint: Because we know the population mean for the American cars but not the standard deviation, we cannot conduct a Z test but should perform a one-sample t-test instead.
