(9 points) 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 sedan models (listed in the table below) to be compared to the American car statistics. The US Environmental Protection Agency reported that the average MPG for American sedans in 2022 is = 26.5 (comparison population mean). Using a significance level of = .05, determine whether the sample data suggests that the MPG for Japanese cars is statistically significantly greater than the MPG for American cars.
