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). These data can also be found in the Excel file activations. xlsx.

a. Construct a scatter plot for these data.

b. Calculate the slope and the y intercept for the regression equation.

c. Provide an interpretation for the value of the slope.

d. Predict the number of activations next week for an employee with a satisfaction level of 7.5.

e. Calculate the SST.

f. Partition the SST into the SSR and the SSE.

g. Verify your results using Excel.
