Description: assume that you have a sample of n1 8 with the sample mean x1 43 and a sample standard deviation of s1 4 and you have an independent sample of n2 12 from another population with a sample mea 43882

Step 1: The formula for the confidence interval for the difference between two population means

Question

Assume that you have a sample of n₁ = 8, with the sample mean X₁ = 43, and a sample standard deviation of S₁ = 4, and you have an independent sample of n₂ = 12 from another population with a sample mean of X2 = 36, and the sample standard deviation S₂ = 8. Construct a 99% confidence interval estimate of the population mean difference between µ₁ and µ₂. Assume that the two population variances are equal. $$ \square \leq \mu_1 - \mu_2 \leq \square $$ (Round to two decimal places as needed.)

          Assume that you have a sample of n₁ = 8, with the sample mean X₁ = 43, and a sample standard deviation of S₁ = 4,
and you have an independent sample of n₂ = 12 from another population with a sample mean of X2 = 36, and the
sample standard deviation S₂ = 8. Construct a 99% confidence interval estimate of the population mean difference
between µ₁ and µ₂. Assume that the two population variances are equal.
