- A university offers supplemental instruction (SI) for introductory chemistry students three times a week. The table below shows the number of SI visits during the semester for a sample of students along with each student's final class average. Use technology to compute a p-value and use it to determine whether the regression equation is useful for making predictions about the benefit of attending SI. Test at the 5% significance level with the hypotheses Ho: B₁ = 0 and H₂: B₁ *0. # of Sl visits 2 8 10 9 15 7 5 4 8 10 7 7 5 4 4 11 Final class average 81 85 76 76 72 72 42 59 81 71 66 88 63 62 61 70 O A. p=0.0325. Since p x, reject the null hypothesis Ho: B₁ = 0. The regression equation is useful for making predictions. O C. p=0.2529. Since p > x, do not reject the null hypothesis Ho: B₁ = 0. The regression equation is not useful for making predictions. O D. p=0.04229. Since p < x, reject the null hypothesis Ho: B₁ = 0. The regression equation is useful for making predictions.The average effect size in social psychology is around d = 0.21. Conventionally, a sample over 30individuals is considered 'large.'

(use the standard alpha)A researcher wanted to examine the effectiveness of Vitamin C on the number of colds a year. The researcher obtained a sample of adults and asked to take Vitamin C daily. The average number of colds a year among adults is known to have the average of μ = 3On the basis of this sample, can the researcher conclude that Vitamin C has an effect on the number of colds a year? Use alpha =.05 two-tailed test. Colds: 2,2,2,1,3,3,1,2 Conducta two-tailed test with alpha = .05. Q1: State your null and research hypotheses using complete sentences Q2: What is the df? Q3: What are the cut-off points Q4: What is the standard deviation? You can just include the answer for the mean, SS, and the standard deviation. No need to type your computation.
