Problem 2

The theater of the city of Mayaguez has a popular concert in schedule and has decided to sells tickets by phone. For that, it needs to decide how many operators to hire for the sale. On one hand, it doesn't want the customers to wait too long, but on the other hand the operators are expensive. The data the manager has collected from previous concerts is as follows.

Operators	Wait Time
4	385
5	335
6	383
7	344
8	288

Specifically, we want to find the linear regression formula between the variables.

If management decides to hire 10 operators, how much waiting time can we expect for the clients?
