You want to know if college students have more stress in their daily lives than the general population (u = 12), so you gather data from 25 people to test your hypothesis. Your sample has an average stress score of xbar = 13.11 and a standard deviation of Sx = 3.89. Using an alpha = .05 and a two-tailed approach, conduct a one-sample t-test to see if there is a difference. O Fail to reject (retain) the null; There is compelling evidence that college students have more stress than the general population. O Reject the null; There is compelling evidence that college students have more stress than the general population. O Reject the null; There is not compelling evidence that college students have more stress than the general population. O Fail to reject (retain) the null; There is not compelling evidence that college students have more stress than the general population.Determine whether you would reject or fail to reject the null hypothesis in the following situations: t = 2.58, N = 21, two-tailed [ Choose ] v test at a = 0.05 t = 1.99, N = 49, one-tailed [ Choose ] v test at a = 0.01 null u = 47.82, 99% CI = [ Choose ] v (48.71, 49.28) null H = 0, 95% CI = (-0.15, [ Choose ] V 0.20)
