3) We are conducting a study in which we wish to calculate a 95% confidence interval for the average difference in starting salaries between XU Biology majors and UC Biology majors. We recruit 10 XU bio majors and 10 UC bio majors. Data are reported below: XU bio majors nXU=10 x̅XU = $45,000 sXU = $5,000 UC bio majors nUC=10 x̅UC = $41,000 sUC = $5,000 Calculate the 95% confidence interval around the average difference in starting salaries between Xavier and UC Biology majors: __________________________________

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...

a. We are testing H0: μ1 - μ2 = 0. Our 95% confidence interval is (-23.95,-7.41). We should expect the t-statistic to be _____( greater than 2 /between 0 and 2/ between 0 and -2 /less than -2) . We should expect the p-value to be _______ (less than .05/ greater than .05/ equal to .05). We should ______(reject /fail to reject)  H0 and conclude that the group 1 population average is _____(smaller/ larger) than the group 2 population average. It...

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...

Using techniques from an earlier section, we can find a confidence interval for μd. Consider a random sample of n matched data pairs A, B. Let d = B − A be a random variable representing the difference between the values in a matched data pair. Compute the sample mean d of the differences and the sample standard deviation sd. If d has a normal distribution or is mound-shaped, or if n ≥ 30, then a confidence interval for μd...
