1. How do the 5-number summaries compare to one another?
2. If you were the homeowner, what would be the most important observation you could make about the difference between the home voltage and the generator voltage?
Amber and Kyle are both managers at a grocery store.
When Amber is on duty, she likes to form a single line for customers. This allows each cashier to help the next available customer. We'll call this a "single line."
When Kyle is on duty, he has each customer choose which line they will get into. We'll call this "multiple lines."
A random sample of customer wait times resulted in the following data:
Single Line 6.7 6 8.1 6.5 5.8 7.2 7.3 7.2 8.2 7
Multiple Lines 7 6.9 4.7 3.2 9.1 9.6 7.4 9.2 5.8 7.1
1.What is the mean for a single line?
What is the mean for multiple lines?
