Question
To construct a confidence interval for the difference between two population means u, - 2, use the formula shown below when both population standard deviations are known, and either both populations are normally distributed or both n 2 30 and n2 2 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. n2 X1 = $108,920, n, = 40, and o, = $8550; x2 = $85,300, n2 = 43, and o2 = $8555 n2 %3D Complete the 95% confidence interval for p,-2 below. %3D (Round to the nearest dollar as needed.)
