A car company claims that its new SUV gets better gas mileage than its competitor’s SUV. A random sample of 32 of its SUVs has a mean gas mileage of 13.6 miles per gallon (mpg). The population standard deviation is known to be 0.5 mpg. A random sample of 47 competitors’ SUVs has a mean gas mileage of 13.4 mpg. The population standard deviation for the competitor is known to be 0.6 mpg. Test the company’s claim at the 0.10 level of significance. Let the car company be Population 1 and let the competitor be Population 2.
