Question

20 vehicle speeds in a 65mph zone are recorded by a laser radar machine: 51, 55, 55, 55, 58, 60, 60, 62, 63, 67, 71, 70, 74, 74, 79, 80, 81, 81, 82, 88 1. Create a Frequency Distribution for Vehicle Speeds in this 65mph zone. Use four classes. 2. Create a Histogram from your above frequency distribution. 3. If you must pick one of the distribution types we covered in class to describe the dataset, which would it be?
