Chapter 9, Problem 75E(choose chapter or problem)
Insomnia and education. Many workers suffer from stress and chronic insomnia. Is insomnia related to education status? Researchers at the Universities of Memphis, Alabama at Birmingham, and Tennessee investigated this question in the Journal of Abnormal Psychology (Feb. 2005). Adults living in Tennessee were selected to participate in the
b. Give a practical interpretation of the test for interaction using α = .05.
c. The F-values (and corresponding p-values) missing in the table were not provided in the journal article. Are these results required to complete the analysis of the data? Explain.
d. In a follow-up to the ANOVA, the researchers compared the mean willing to pay values for the homogeneous and mixed-menu conditions at each level of the order condition. In the virtue condition, the mean for the homogeneous menu ($11.08) was significantly lower than the mean for the mixed menu ($13.26). In the vice condition, the mean for the homogeneous menu ($17.11) was significantly higher than the mean for the mixed menu ($15.00). Demonstrate why these results support your answer to part b. Illustrate with a graph.
