Using techniques from an earlier section, we can find a confidence interval for u. 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 has a normal distribution or is mound-shaped, or if n 2 30, then a confidence interval for l, is as follows. If d a - E< Hg

A professor wants to know whether or not there is a difference in comprehension of a lab assignment among students depending on if the instructions are given all in text, or if they are given primarily with visual illustrations. She randomly divides her class into two groups of 15, gives one group instructions in text and the second group instructions with visual illustrations. The following data summarizes the scores the students received on a test given after the lab. Let the populations be normally distributed with a population standard deviation of 5.32 points for both the text and visual illustrations.
