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 men and 10 women for the study. The sample results are: men n1=10 students, xbar1=2.7 hours, s1= .30hours,
women n2=10 students, xbar2=2.4 hours. s2= .40hours
Based on these data, the point estimate is .30 hours.
