A car company claims that its new SUV gets better gas mileage
than its competitor’s SUV. A random sample of 48 of its SUVs
has a mean gas mileage of 16.1 miles per gallon (mpg). The
population standard deviation is known to be 0.7 mpg. A random
sample of 33 competitor’s SUVs has a mean gas mileage
of 15.8 mpg. The population standard deviation for the
competitor is known to be 0.8 mpg. Test the company’s claim at
the 0.01 level of significance. Let the car company's SUVs be
Population 1 and let the competitor's SUVs be Population 2.
