Thank you for your help A car company claims that its new SUV gets better gas mileage than its competitor's SUV. A random sample of 44 of its SUVs has a mean gas mileage of 15.4 miles per gallon (mpg). The population standard deviation is known to be 1.4 mpg. A random sample of 49 competitor's SUVs has a mean gas mileage of 14.9 mpg. The population standard deviation for the competitor is known to be 0,5 mpg. Test the company's claim at the 0.10 level of significance. Let the car company's SUVs be Population 1 and let the competitor's SUVs be Population 2. Compute the value of the test statistic. Round your answer to two decimal places.
