Construct the indicated confidence interval for the difference between the two population means. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Independent samples from two different populations yield the following data. The sample size is 478 for both samples. Find the \(85 \%\) confidence interval for \(\mu_{1}-\mu_{2}\). \(\bar{x}_{1}=958, \bar{x}_{2}=157, s_{1}=77, s_{2}=88\) A. \(800<\mu_{1}-\mu_{2}<802\) B. \(791<\mu_{1}-\mu_{2}<811\) C. \(793<\mu_{1}-\mu_{2}<809\) D. \(781<\mu_{1}-\mu_{2}<821\)

Construct the indicated confidence interval for the difference between the two population means. Assume that the two samples are independent simple random samples selected from normally distributed populations. Also assume that the population standard deviations are equal (sigma1 = sigma2), so that the standard error of the difference between means is obtained by pooling the sample variances. A paint manufacturer wanted to compare the drying times of two different types of paint. Independent simple random samples of 11 cans of...
