Calculate the 95% confidence interval for the difference (mu1-mu2) of two population means given the following sampling results. Population 1: sample size = 18, sample mean = 26.66, sample standard deviation = 1.04. Population 2: sample size = 15, sample mean = 10.79, sample standard deviation = 1.71.

You want to calculate a 95% confidence interval (CI) for the difference between the means of two variables. The variables are from populations with normal distributions and those distributions have the same standard deviation (σ). To make your estimate you will take the same number of samples from each population, calculate the mean for each sample, calculate the difference between those sample means, and then add or subtract the term that defines the CI. If you want the width of...

Suppose you calculate a 95% confidence interval for the difference in population means. The confidence interval contains both negative and positive values. Will a 99% confidence interval based on the same data contain both negative and positive numbers as well? Choose the correct response from the options provided below. Yes. Keeping all other values the same, increasing the confidence level leads to a wider interval which would still include negative and positive numbers. No. Increasing the confidence level leads to...
