Question

Boston Electric Generators has been getting many complaints from its major customer, Home Station, about the quality of its shipments of home generators. Daniel Shimshak, the plant manager, is alarmed that a customer is providing him with the only information the company has on shipment quality. He decides to collect information on defective shipments through a form he has asked his drivers to complete on arrival at customers’ stores. The forms for the first 279 shipments have been turned in. They show the following over the past 8 weeks:

WEEK NO. OF NO. OF SHIPMENTS REASON FOR DEFECTIVE SHIPMENT
SHIPMENTS WITH DEFECTS INCORRECT BILL INCORRECT DAMAGED TRUCKS
OF LADING TRUCK-LOAD PRODUCT LATE
1 23 5 2 2 1
2 31 8 1 4 1 2
3 28 6 2 3 1
4 37 11 4 4 1 2
5 35 10 3 4 2 1
6 40 14 5 6 3
7 41 12 3 5 3 1
8 44 15 4 7 2 2

Even though Daniel increased his capacity by adding more workers to his normal contingent of 30, he knew that for many weeks he exceeded his regular output of 30 shipments per week. A review of his turnover over the past 8 weeks shows the following:

WEEK NO. OF NEW HIRES NO. OF TERMINATIONS TOTAL NO. OF WORKERS
1 1 0 30
2 2 1 31
3 3 2 32
4 2 0 34
5 2 2 34
6 2 4 32
7 4 1 35
8 3 2 36

Develop a scatter diagram using total number of shipments and number of defective shipments. Does there appear to be any relationship?

Answer 1

To develop a scatter diagram using the total number of shipments and the number of defective shipments, plot the data points for each week on the x and y-axis respectively. Analyze the scatter plot to determine if there is a relationship.

Step-by-step explanation:

To develop a scatter diagram using the total number of shipments and the number of defective shipments, we will plot the data points for each week. The total number of shipments will be on the x-axis, and the number of defective shipments will be on the y-axis. Each data point will represent one week of shipments. By analyzing the scatter plot, we can determine if there is any relationship between the total number of shipments and the number of defective shipments. If the data points form a clear pattern or trend, it indicates a relationship.
