Question

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 least 6 items?

Answer 1

The frequency of times the '10 items or less' limit was exceeded by at least 6 items is 10.

Step-by-step explanation:

The histogram shows the frequency of customers violating the '10 items or less' rule by placing a certain number of items over the limit on the conveyor belt.

To determine the frequency of times the limit was exceeded by at least 6 items, we need to add up the frequencies for the classes that represent 6 or more items.

In this histogram, the classes that represent 6 or more items are 6.5-7.5 and 7.5 and above.

The frequencies for these classes are 6 and 4, respectively.

Therefore, the frequency of times the limit was exceeded by at least 6 items is 6 + 4 = 10.
