between two population means μ1−μ2...

To construct a confidence interval for the difference between two population means μ1−μ2, use the formula shown below when both population standard deviations are known, and either both populations are normally distributed or both n1≥30 and n2≥30. Also, the samples must be randomly selected and independent.The descriptive statistics for the annual salaries from a random sample of microbiologists from two regions are shown below. Construct a 95% confidence interval for the difference between the mean annual salaries.x1=$102,340, n1=40, and σ1=$8635; x2=$85,110, n2=35, and σ2=$86251.Complete the 95% confidence interval for μ1−μ2 below.$______<μ1−μ2<$_______(Round to the nearest dollar as needed.)
