Transcribed Image Text:**Title: Analyzing Appliance Usage and Report Accuracy**
Jeff Friedman was a section chief for an electric utility company. After discrepancies in his reports, he was reassigned to the home economics department. Jeff interviewed 128 people at a suburban shopping center to learn about their cooking habits. Here are his findings:
- 55 use microwave ovens
- 66 use electric ranges
- 58 use gas ranges
- 10 use microwave ovens and electric ranges
- 24 use microwave ovens and gas ranges
- 8 use both gas and electric ranges
- 1 uses all three appliances
- 2 use none of the three
**Question for Analysis:**
Should Jeff be reassigned once more? Why or why not?
**Options for Consideration:**
- **A.** Yes, he should be reassigned. He reported interviewing 128 people, but his data suggest otherwise, indicating an error was made.
- **B.** No, he should not be reassigned. His report and the total number of interviews align, showing no error was made.
Consider the insights from Jeff's report and evaluate whether the data he presented indeed reconcile to confirm the total number of participants or reveal a reporting error.
