A homeowner recorded the speeds of cars driving past his house, where the speed limit is 20 mph. The mean of 100 readings was 23.78 mph, with a standard deviation of 3.46 mph. (The homeowner actually recorded every car for a two-month period. These are 100 representative readings.) Suppose police set up radar surveillance on the street. For the many speeders who got tickets the mean was 28 mph, with a standard deviation of 2.6 mph, a maximum of 34 mph, and an IQR of 3.4 mph. Local law prescribes fines of $100, plus $8 per mile per hour over the 20 mph speed limit. For example, a driver convicted of going 25 mph would be fined $100 + $8(5) = $140. Find the mean, standard deviation, maximum, and IQR of all the potential fines. . . The mean of all the potential fines is $ (Round to the nearest cent as needed.) The maximum price of all the potential fines is $ (Round to the nearest cent as needed.) The standard deviation of all the potential fines is $ (Round to the nearest cent as needed.) The IQR of all the potential fines is $ (Round to the nearest cent as needed.)
