A hamburger chain sells large hamburgers. When we take a sample of 40 hamburgers and weigh them, we find that the mean is 0.57 pounds and the standard deviation is 0.1 pound. a. A technology input menu for calculating a confidence interval requires a sample size, a sample mean, and a sample standard deviation. State how you would fill in these numbers. b. Using the accompanying technology output, report the confidence interval in a carefully worded sentence. Click here to view the technology output. C a.
