Atire manufacturer is considering a newly designed tread pattern for its all-weather tires. tests have indicated that these tires will provide better gas mileage and longer tread life. the last remaining test is for braking effectiveness. the company hopes the tire will allow a car traveling at 60 mph to come to a complete stop within an average of 125 feet after the brakes are applied. they will adopt the new tread pattern unless there is strong evidence that the tires do not meet this objective. the distances (in feet) for 10 stops on a test track were 129, 128, 130, 132, 135, 123, 102, 125, 128, and 130. should the company adopt the new tread pattern? test an appropriate hypothesis and state your conclusion. explain how you dealt with the outlier and why you made the recommendation you did.

Suppose that fizzo and pop hop are the only two firms that sell orange soda. the following payoff matrix shows the profit (in millions of dollars) each company will earn depending on whether or not it advertises: pop hopadvertise doesn’t advertisefizzo advertise 10, 10 18, 2doesn’t advertise 2, 18 11, 11for example, the upper right cell shows that if fizzo advertises and pop hop doesn't advertise, fizzo will make a profit of $18 million, and pop hop will make a profit of $2 million. assume this is a simultaneous game and that fizzo and pop hop are both profit-maximizing firms. if fizzo decides to advertise, it will earn a profit if pop hop advertises and a profit if pop hop does not advertise. if fizzo decides not to advertise, it will earn a profit if pop hop advertises and a profit if pop hop does not advertise. if pop hop advertises, fizzo makes a higher profit if it chooses (not to advertise, to .if pop hop doesn't advertise, fizzo makes a higher profit if it chooses (not to advertise, to . suppose that both firms start off not advertising. if the firms act independently, what strategies will they end up choosing? fizzo will choose to advertise and pop hop will choose not to advertise. both firms will choose to advertise. fizzo will choose not to advertise and pop hop will choose to advertise. both firms will choose not to advertise. again, suppose that both firms start off not advertising. if the firms decide to collude, what strategies will they end up choosing? fizzo will choose not to advertise and pop hop will choose to advertise. both firms will choose not to advertise. fizzo will choose to advertise and pop hop will choose not to advertise. both firms will choose to advertise.
