Use the data in the table and submit the answers to the following questions in a Word document:
What was the average effect of the process change? Did the process average increase or decrease, and by how much?
Analyze the data using the regression model y= b0 + b1 x, where y = time to approve and mail a claim (weekly average), x = 0 for the old process, and x = 1 for the new process.
How does this model measure the effect of the process change?
How much did the process performance change on the average? (Hint: Compare the values of b1 and the average of new process performance minus the average of the performance of the old process.)
