You're a research analyst for General Motors. You want to know if there a difference in the average miles per gallon (mpg) of two car models, a sedan and a van. You randomly select samples from each model, with results as follows. At the 1% significance level, do sedans get better mileage than vans? Sedan Van Number 160 100 Mean (mpg) 22.00 20.27 Std Dev (mpg) 8.06 2.24
