A training center, wishing to demonstrate the effectiveness of their methods, tests some of their clients after different numbers of days of training, recording their scores on a sample test. Their data are:

The regression model they calculate is Correct responses = 3.525 + 0.525 Training days.

a) Use the model to predict the correct responses for each number of training days.

b) Find the residuals, ei.

c) Calculate the residual standard deviation, se.
