## 24. I did an eggsperiment with a fellow instructor one day. His calculus class was studying volumes of solids by rotating curves around the x-axis. We modeled the volume of an egg as an ellipsoid, and measured eggs with calipers, using the calculus formula. Each egg was also measured for volume using a water displacement method. We wanted to know if the two methods agreed or not. The data were A 95% confidence interval for the average difference (calculus – water) is a. (-1.69, 5.04) b. (-7.54, 10.90) c. (-2.29, 5.64)
