A reseаrcher wаnts tо knоw whether three different brief heаlth educatiоn programs differ in how well they reduce patients’ stress. Patients are randomly assigned to one of three programs: a cognitive-behavioral education program, a sleep hygiene program, or a relaxation training program. After completing the program, each patient reports how much their stress decreased on a 1–15 scale, with higher scores meaning greater stress reduction.Calculate F using a one-way ANOVA. Use a .05 alpha level.You do not need to calculate HSD or effect size d for this problem.Cognitive-Behavioral     Sleep Hygiene         Relaxation Training12                                         13                              610                                           4                              511                                           9                              89                                              6                             27                                            12                             23                                            10                             1Copy/paste this and include your answers:SStot:SS treat:SS error:MStreat:MSerror:Calculated F:Critical F:Interpretation:
