= 1. Mean hours studied by two independent groups of students are displayed below: Sample l: Student athletes ni = 65; sample mean (xi-bar) = 20.6; S1 = 5.25 Sample II: Student non-athletes n2 = 175; sample mean (x2-bar) = 23.5; $2 = 3.85 (a) Do these samples provide sufficient evidence to conclude that the population mean hours of non-athletes and athletes differ? Use a=0.10. (b) Find the observed significance probability. (c) Also, find a 95% confidence interval for Mi M2.
