I mean after all I saw on the news last year about that psychologist who was killed by her client. You talk with your friend about the topic and then decide to look into some studies about people with mental illness and aggression towards therapists. What you are trying to do is overcome...

    14. The results of a one-way ANOVA are presented in an article. The researchers studied the effects of participating in in-person smoking cessation support groups vs. participating in on-line smoking cessation support groups on amount of time participants stopped smoking. They followed up on the participants for one year (so participants could score between 0-12 months in smoking cessation). There were equal numbers of participants in each type of intervention group. The results were F (1, 146) = 14.55, p = .002. Based on that information you know that there were how many people participated in the on-line smoking cessation support group?

    A 144

    B 146

    C 74

    D Can't tell from this information

    15. Based on the smoking cessation study described in the last question, if the amount of time before participants in the on-line groups began smoking again had a mean score of 5.8 months while the amount of time before participants in the in-perseon groups began smoking again had a mean score of 10.7 months (and you have the information from the last question too). Then what can you conclude?

    A. On-line smoking cessation groups are not effective
    B. This study supported the use of in-person smoking cessation groups
    C. The null hypothesis was accepted
    D. There was no difference between on-line and in-person smoking cessation groups.
