General Motors and Ford have produced cars with the same size in determining whether or not there is a significant difference in the gas consumption of the two models of automobiles. A random sample of 7 cars from each manufacturer is selected, and 7 drivers are selected to drive one of GM and one of Ford cars for a specified distance implying that driver 1 drove the first GM car and the first Ford car, driver 2 drove the second GM car and the second Ford car, driver 3 drove third GM car and the third Ford car, and so on. The MPG (miles per gallon) data is recorded and summarized in the following table: Which of the following is a correct statement if the objective of the test of hypothesis is to determine whether there is a difference in the gas consumption of the two models? Select one: A. HO:CM=Ford B. H0:D=0 (where D is the mean population difference) Which of the following is a correct statement if the objective of the test of hypothesis is to determine whether there is a difference in the gas consumption of the two models? Select one: A. H0:GM=Ford B. H0:D=0 (where D is the mean population difference) C. H0:GMFord D. H0:D0 E. None of the above answers is correct
