According to an automobile association, the average cost of a gallon of regular unleaded fuel at gas stations in a certain month was $2 827. Assume that the standard deviation of such costs is $0 15. Suppose that a random sample of n100 gas stations is selected from the population and the month's cost per gallion of regular unleaded fuel is determined for each Considor & the sample mean cost per gallon.

O words Question 21 8 pts A test team takes readings from the miles per gallon (mpg) estimate reading in a new car while driving at 60 mph. The sample consists of 30 readings and has a mean of 31.3 mpg and a standard deviation of 117 mpg. The average mpg of all new cars is 27.6 mpg although the standard deviation is unknown. Is there evidence the new car has superior gas mileage? Conduct a test of significance stating...
