The NCAA is interested in estimating the difference in mean number
of daily training hours for men and women athletes on college
campuses. It wants 95 percent confidence and will select a sample
of 10 men and 10 women for the study. The variances are assumed
equal and the populations normally distributed. The sample results
are:
| Men | Women |
|
n1 = 10 students |
n2 = 10 students |
|
2.7 hours |
2.4 hours |
|
s1 = .30 hours |
s2 = .40 hours |
Based on these data, the lower limit for the difference between
population means is 0.15 hours.
| true |
| false |
