assume that the polpulation distribution of times (in minutes) for two different skiers to race the same course are normal at equal variances.

Two random samples, drawn independently from the population, showed the following statistics

n, = 4, x₁ , = 7.52, S₁² , = 0.25

n₂ = 5, x₂ = 8.37, S₂² = 0.09

construct and interpret a 95% confidence interval for the time difference in average time of skiers to race the same course
