Three students measure the width of your table top three times and record the following data: Student A - 4.0 ft, 3.5 ft, 4.5 ft
Student B - 4.1 ft. 4.2 ft, 3.7 ft
Student C-40 ft 4.1 ft, 3.9 ft
1. Find the average width of the table for each student, and then determine the
range of data for each student
