Construct a 99% confidence interval for H1 H2 with the sample statistics for mean cholesterol content of a hamburger from two fast food chains and confidence interval
construction formula below. Assume the populations are approximately normal with unequal variances.
Stats
x₁ = 135 mg, s₁ = 3.82 mg, n₁ = 18
Confidence interval when (x-2)-
variances are not equal

n₁
Ոշ
п1 ոշ
d.f. is the smaller of n₁ - 1 or 2 - 1
x2=121 mg, s₂ = 2.02 mg, n₂ = 16
Enter the endpoints of the interval.
