As a measure of productivity, Verizon Wireless records the number of customers each of its retail employees activates weekly. An activation is defined as either a new customer signing a cell phone contract or an existing customer renewing a contract. The following table shows the number of weekly activations for eight randomly selected employees along with their job-satisfaction levels rated on a scale of 1-10 (10 = Most satisfied).

Satisfaction	Activations
8	36
7.9	25
8.5	40
9	38
6.1	19
7	28
8.2	33
7.7	25

These data can also be found in the Excel file activations.xlsx Download activations.xlsx. Suppose a simple regression model is constructed to explain the number of weekly activations for an employee (C) with the employees satisfaction level (S).
