10. LIGHT AT NIGHT MAKES FAT MICE Studies have shown that exposure to light at night is harmful to human health. A study in mice shows that light at night has an effect on weight gain after just three weeks. In the study, mice were randomly assigned to live in one of three light conditions: LD had a standard light/dark cycle, LL had bright light all the time, and DM had dim light when there normally would have been darkness. Activity Levels Perhaps the mice with light at night gain more weight because they are exercising less. The conditions for an ANOVA test are met and computer output is shown for testing the average activity level for each of the three light conditions. The null hypothesis is that mean activity level is not related to light condition, while the alternative hypothesis is that the mean activity level is related to light condition. Is there a significant difference in mean activity level? a. What is the F-Statistic: __________________ [2pts] b. What is the p-value: ____________________ [2pts] c.
