Refer to the following scenario to answer questions that follow it People often report having bad dreams when they eat just before going to sleep. A sleep researcher wanted to see if this was really true. Twelve participants agreed to report to the sleep lab at 8 p.m. and sleep there every night for a week. Participants were randomly assigned to one of the four conditions: 1) to not eat before bed, 2) to eat a light snack before bed, 3) to eat a light meal before bed, and 4) to eat a heavy meal before bed. During the week, the number of bad dreams for each participant was recorded. Use these data to conduct an analysis of variance. To help with the mean square bg and mean square within groups use the following: Sums of squares between groups is =1,688 and Sums of Squares withing groups is 10,75 No Meal Light Snack Light Meal Heavy Meal 0 3 3 1 1 1 0 1 1 2 2 1 1 Question 1: Which of the following is the null hypothesis for this study? O Ho : M1 - 12 - 13 # 0 O Ho: HI - 12 - 13 - MA # 0 O Ho: HI - 12 - 13 = 0 O HO:M1 - M2 - 13 - 14 = 0 What is the F ratio for these data? A. .611 B. 1.00 C. .226 . .628
