Question
Given two independent random samples with the following results:
n₂ = 8
x₂ = 124
$2 = 28
= 16
n₁
x₁ = 94
$1 = 16
Use this data to find the 90 % confidence interval for the true difference between the population means.
Assume that the population variances are equal and that the two populations are normally distributed.
