You are in the market for a new car. You want to check whether there is a significant difference between the fuel economy of mid-size domestic cars and mid-size import cars. You sample 24 domestic car makes and find an average fuel economy of 35.696 MPG with a standard deviation of 4.931 MPG. For imports, you sample 16 cars and find an average MPG of 34.345 MPG with a standard deviation of 7.118. If a 90% confidence interval is calculated to estimate the difference between the average fuel economy of domestic and import mid-size cars, what is the margin of error
