Two levels (low and high) of insulin doses are given to two groups of diabetic rats tea

Question:

Two levels (low and high) of insulin doses are given to two groups of diabetic rats tea check the insulin binding capacity, yielding the following data:

Low dose: n₁ = 8 x₁ — 1.98 S₁ = 0.51

High dose: n₂ = 13 x₂ = 1.30 8a = 0.35

Assume that both variances are equal. Give a 95% confidence interval for the difference of the true average insulin-binding capacity between two samples.
