One way analysis of variance

D Question 29 3 pts Lesson 15: One-Way Analysis of Variance A psychophysiologist is trying to determine whether MDMA (ecstasy) causes more brain cell loss than alcohol. Four rats are exposed to either MDMA, alcohol, or a placebo for 10 weeks. At the end of the 10 weeks the brains' of each animal is inspected for cell loss. Use the data below to answer questions 29-35. MDMA Alcohol Placebo 30 10 5 22 15 10 26 10 15 23 20 5 Mean 25.25 13.75 8.75 SD 3.59 4.79 4.79 29. What is the SSbg? 0 63.63 572.667 O 286.333 O 176.25 O 212.76Question 33 33. What are the dfwg? 0 2 0 6 0 1 O 12 0 9 Question 34 34. What is the critical F value at p = 0.05? O 8.55 O 19.38 O 4.26 O 2.90 O 4.88D Question 34 34. What is the critical F value at p = 0.05? O 8.55 19.38 O 4.26 O 2.90 O 4.88. D Question 35 35. What do you conclude? O Since the calculated F value exceeds the critical F value, then we fail to reject the null hypothesis. Since the calculated F value exceeds the critical F value, then we can reject the null hypothesis. Since the calculated F value does not exceed the critical F value, then we can reject the null hypothesis. Since the calculated F value does not exceed the critical F value, then we fail to reject the null hypothesis.
