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. Q5: What is the estimated standard error? Show your computation. Q6: What is the t-value? Show your computation. Q7: State your conclusion thoroughly.
