Use the following information to answer the question. Researchers want to test whether the color of a vehicle ticketed for speeding has an effect on the amount of the ticket. Four vehicle colors were used for the study--red, white, black, and silver. Thirty vehicles were randomly assigned to each group. Use the output below to answer the question. Choose the correct conclusion for the hypothesis that vehicle color affects the amount of a speeding ticket. Assume all ANOVA test conditions have been satisfied. a) Reject H0. The vehicle color has no effect on the amount of the speeding ticket. b) Fail to reject H0. The vehicle color has no effect on the amount of the speeding ticket. c) Reject H0. The vehicle color has an effect on the amount of the speeding ticket. d) Fail to reject H0. The vehicle color has an effect on the amount of the speeding ticket.
A researcher has observed 500 vehicles at a stop sign in a suburban neighbourhood and recorded the type of vehicle (sedan, hatchback, bakkie) and driver behaviour at the stop sign (complete stop, near stop, “ran” the stop sign). At the 0.05 level of significance, could there be some relationship between driver behaviour and the type of vehicle being driven? Define the null hypothesis and the alternative hypothesis. A. H1: Driver’s behaviour and type of vehicle are independent vs H0: A relationship exists between driver’s behaviour and type of vehicle B. H0: A relationship exists between driver’s behaviour and type of vehicle vs H1: No relationship exists between driver’s behaviour and type of vehicle C. H0: Driver’s behaviour and dependent on the type of vehicle vs H1: Driver’s behaviour and type of vehicle are independent D. H0: Driver’s behaviour and type of vehicle are independent vs H1: A relationship exists between driver’s behaviour and type of vehicle
