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 less than 3 items?

Answer 1

Given data shows the frequency of the items over the limit each violator placed on the conveyor belt is shown.

Here,we need to determine the frequency of the times the limit was exceeded by less than 3 items is -

from the given histogram graph,we have frequency distribution as follows:-

frequency from 0.5-1.5 is " 7"

frequency from 1.5 t to 2.5 is "10 "

frequency from 2.5 to 3.5 is " 11"

So,the frequency of times the limit was exceeded by less than 3 items is

frequency less than 3 items= 7+10+11 =28

So the frequency of times the limit was exceeded by less than 3 items is ( 28 ).

ANSWER :: 28
