A researcher conducts an independent-measures study examiningthe effectiveness of a group exercise program at an assisted livingfacility for elderly adults. One group of residents is selected toparticipate in the program, and a second group serves as a control.After 6 weeks, the researcher assessed physical fitness of eachparticipant.
The data are as follows: Exercise Group: Control Group: n = 15 n= 15 M = 37 M = 34 SS = 230 SS = 160 A. Does the exercise programhave a significant effect on physical fitness? Use p < .05,2-tails test.
B. If there is a significant effect, compute the estimatedCohen’s d to measure the size of the treatment effect.
C. Write a conclusion demonstrating how the outcome of thehypothesis test and the measure of effect size would appear in aresearch report in APA style.
Note: For full credit show all steps of hypothesis testing(i.e., write hypotheses, all computations, the tcritical used forthe decision about H0 and the conclusion in APA reportingformat).
