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 more than 5 items?

Answer 1

From the Histogram we Construct the Frequency Distirbution

C. I	f
0.5 - 1.5	6
1.5 - 2.5	10
2.5 - 3.5	14
3.5 - 4.5	12
4.5 - 5.5	10
5.5 - 6.5	8
6.5 - 7.5	5
TOTAL	65

From this We constuct the Greater than Cumulative Frequency Distribution

GLB	GCF
	65
	59
	49
	35
	23
	13
	5

Frequency of the times the limit was exceed by more than 5 items is "13".
