When only two treatments are involved, ANOVA and the Student's t test (Chapter 11) result in the same conclusions. Also, for computed test statistics, t F. To demonstrate this relationship, use the following example. Fourteen randomly selected students enrolled in a history course were divided into two groups, one consisting of 6 students who took the course in the normal lecture format. The other group of 8 students took the course as a distance course format. At the end of...

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. One-way ANOVA Variation between groups=2063.33 Variation within groups=196.25 p=4.5985705E-4 Choose the correct conclusion for the hypothesis that vehicle color affects the amount...
