Based on the APA formatted statements below, give the type of research design (between subjects/within subjects), the sample size, and the decision (reject the null hypothesis/fail to reject the null hypothesis) in this study? NOTE: I need the three pieces of information with steps.
. A social psychologist records the number of outbursts in a sample of different classrooms at a local school.
The number of outbursts among students at a local school (M = 3) were significantly less than that in the general population, t(39) = 4.19, p<.05, d = 0.25

Conduct an independent samples t-test (a.k.a., between-subjects design). Each sample should have at least n=8 individuals. What to turn in: 1. What is your research question? 2. State the null (Ho) and alternative (H1) hypotheses. 3. Conduct the hypothesis test using an alpha level of .05, and state your conclusion (Reject Ho/Fail to Reject Ho) regarding the original hypotheses. 4. Calculate and interpret a measure of effect size (est. Cohen's d or r2) and a 95% confidence interval.

Styles ANOVA One-Way Within-Subjects Design 1. A group of clinicians who are members of the U.S. military are concerned with the morale of troops serving in war regions. They hypothesize that the number of tours a soldier has served significantly affects morale. To test this hypothesis, they select a sample of eight soldiers who served three tours in war regions and ask them to rate their morale during each tour they served in. Lower ratings indicate lower morale. The table...
