Suppose eight cars are first driven with type A fuel and then (after the gas tank is cleaned) driven with fuel of type B. The data on emissions level of each car are given below: Car 1: 8, 10.7; Car 2: 7, 11; Car 3: 10.2, 12.9, Car 4: 9, 10; Car 5: 13, 14; Car6: 12, 9.5; Car 7: 10.8, 14; Car 8: 11.2, 15 Use an appropriate procedure to analyze the data. Suppose you were told to ignore the matching (pairing) of the data and treat the emissions levels of cars of type A and type B as two independent samples. Carry out an appropriate test and compare the conclusions you obtained from the two analyses. Which is correct? Explain your
