The NCAA is interested in estimating the difference in mean number of daily training hours for men and women athletes on college campuses. They want 95 percent confidence and will select a sample of 10 me and 10 women for the study. The sample results are: Men Women 01 = 10 students n2 = 10 students X1=2.7hours 2.4hours X2 s1 = .30 hours s2 = .40 hours Based on these data calculate: a) point estimate p) pooled standard deviation c) t-critical value with 95% confidence H) the 95% confidence interval for the diference between two groups
