Please provide answers from question 9 till the end

__ 1. An AN OVA is used to evaluate the mean differences among three treatment conditions with a sample of n = 12 participants in each treatment. For this study, what is dftotal? a. 2 b. c. d. 11 33 35 2. In an analysis of variance, which of the following is not true? a. SStotal = SSbetween + SSwithin b. dftotal = dfbetween + dfWithin c. d. MStotal = MSbetween + MSSwithin All three choices are true. 3. An analysis of variance produces SStotal = 80 and SSwithin = 30. For this analysis, what is SSbetween? a. 30 b. 50 c. 110 d. Cannot be determined without additional information 4. An AN OVA is used to evaluate the mean differences among three treatment conditions with a sample of n = 12 participants in each treatment. For this study, what is dfbetween treatments? a. 2 b. c. d. 11 33 35 5. A researcher reports an F-ratio with df= 2, 18 from an independent-measures research study. Based on the dfvalues, how many treatments were compared in the study, and what was the total number of subjects participating in the study? a. 2 treatments and 19 subjects b. c. d. 2 treatments and 20 subjects 3 treatments and 21 subjects 3 treatments and 22 subjects 6. For an ANOV A comparing three treatment conditions, what is stated by the null hypothesis (HO)? a. There are no differences between any of the population means. b. c. d. At least one of the three population means is different from another mean. All three of the population means are different from each other. None of the other choices is correct. 7. A research study comparing three treatments with n = 5 in each treatment produces T1 = 5, T2 = 10, T3 = 15, with SSI = 6, SS2 = 9, SS3 = 9, and LX2 = 94. For this study, what is SSwithin? a. b. c. d. 10 24 34 68 8. In analysis of variance, what is measured by the MS values? Page 1 of_8 J a. b. c. d. Sample variance Population variance The average distance from one mean to another The total variability for the se: of-res 9.
