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.
