A researcher wants to determine whether  the type of gasoline  used in a car affects the gas mileage. Gas mileage is also affected by car type and driver. The researcher selects five different types of car and assigns a driver to each car.  For each car (and driver), the researcher randomly selects  the sequence in which the different gasoline types will be used. The mileage for each car/gasoline combination was determined by filling the car with 3 gallons of the specified gasoline, driving the car around a race track until the gas tank was empty, and dividing the number of miles driven by the number of gallons used. The results are shown in the table.  The mileages are given in miles per gallon. Let μ1 be the mean for gasoline A, μ2 the mean for gasoline B, and μ3 the mean for gasoline C. In a test of H0: μ1 = μ2 = μ3 versus H1: at least one of the means is different, the null hypothesis is rejected at the α = 0.05 level of significance. Use Tukey's test to determine which pairwise means differ using a familywise error rate of Give the P-value for each of the pairwise tests and state your conclusion.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
