- A data set with whole numbers has a low value of 20 and a high value of 89.Find the class width for a frequency table with seven classes.During one shift, the express lane clerk recorded how many times customers violated the "10 items or less" rule for his lane. In particular, he recorded how many items over the limit each violator placed on the conveyor belt. This data is summarized in the histogram below. NOTE: The last class actually represents "7 or more items," not just 7 items. What is the frequency of times the limit was exceeded by at most 5 items?Answer: timesA data set with whole numbers has a low value of 10 and a high value of 120. Find the class width and class limits for a frequency table with 5 classes.
