A water park has an 18-minute ride through man-made rapids and waterfalls. When the ride is in full operation, riding times for passengers are uniformly distributed between 0 and 18 minutes. Suppose an electrical problem leads to a temporary stoppage. What percent of the riders had been on the ride for less than 2 minutes when the stoppage occured? And what percent of the riders had been on the ride between 10 and 15 minutes when the stoppage occured?

What is the optimal time for a scuba diver to be on the bottom of the ocean? That depends on the depth of the dive. The U.S. Navy has done a lot of research on this topic. The Navy defines the "optimal time" to be the time at each depth for the best balance between length of work period and decompression time after surfacing. Let x = depth of dive in meters, and let y optimal time in hours. A random sample of divers gave the following data. 15.1 23.3 32.2 38.3 51.3 20.5 22.7 2.48 2.38 1.48 1.03 0.75 2.38 2.20 (a) Find Ex, Ey, Ex², Ey², Exy, and r. (Roundr to three decimal places.)
