A traffic-safety researcher is studying driver’s behavior (complete stop, coasting stop, ran stop sign) at a specific stop sign. The researcher would like to know if driver behavior depends on the type of vehicle (car, sport utility vehicle [SUV], pickup truck).   a) What is the appropriate null and alternate hypothesis to determine if stop sign behavior depends on type of vehicle?  b) The traffic-safety researcher observes 500 vehicles at the stop sign and records the two variables: the type of vehicle (car, sport utility vehicle [SUV], pickup truck) and the driver’s behavior at the stop sign (complete stop, coasting stop, ran stop sign).  The data appears below. Use JMP software to test the hypothesis of part a). c)  Using alpha= 0.05, draw a conclusion for the hypothesis test and state the conclusion in the context of the problem.
