Assuming homoscedastic errors, test the hypothesis that age affects charitable donations at the 5% level. 2. Interpret the coefficient on gender interacted with age. 3. How would you test that the difference in giving between men and women is independent of age? If you can run the test, run it. If you cannot, explain what you need.Which MS Excel Tool shall be used with this problem? Dr. Hess has done work that suggests that emotional arousal affects pupil size. To ascertain if the type of arousal makes a difference, you decided to measure pupil size under three different arousal conditions (Neutral, Pleasant, Aversive). Each participant will look at all the different pictures that differ according to the condition. The pupil size after viewing each photograph is measured in millimeters. * ANOVA Single Factor ANOVA Two Factor Without Replication ANOVA Two Factor With Replication A researcher wants to examine driving performance under three telephone conditions namely: a) No Phone, b) Hand-Held, and c) Hands- Free. If he wants to measure the differences between sample means, we will calculate the variance: * both A and B between treatments within-treatments None of the abovecan ridge regression be applied if sample size is smaller than the number of predictors?
