Assume That the Population Distributions of Times (In Minutes) for Two

Short Answer

Assume that the population distributions of times (in minutes) for two different skiers to race the same course are normal with equal variances. Two random samples, drawn independently from the populations, showed the following statistics. Construct and interpret a 95% confidence interval for the true difference in average time of skiers to race the same course.
What is the 95% confidence interval? (CI)
CI = ______________ Enter (n1, n2)
The sample evidence ______________ support that the two skiers, on average, have different race times.
