V Quizzes Dr. Maxwell is trying to determine whether there are differences between four different approaches to treating alcohol misuse in those people experiencing homelessness. There are four programs, each having 20 randomly assigned subjects in each. Each group is equal at the start. The number of days each subject goes without drinking is recorded. Group means (and SDs) are reported below. Sobriety Approach Mean Days Without a Drink Good Samaritan 16.85 (4.33) Volunteers of America 12.60 (4.31) Curtis Shelter 7.45 (4.80) Welton Gives 29.20 (10.38) Given these data, please complete the ANOVA table. Please enter values to second decimal place.

Good Sam * VOA * Curtis * Welton B. Good Sam = VOA = Curtis = Welton C. Good Sam * VOA = Curtis = Welton D. Good Sam = VOA * Curtis * Welton Enter the letter of your choice into the box: Given the outcome you have observed from the F calculated above, make a decision about the null: A. Fail to reject the null; cannot be certain all groups are different B. Reject the null, groups are not equal to each other C. Fail to reject the null; only one group is different D. Accept the null; all groups are equal Please enter the letter of your choice here
