A golf ball is dropped from 15 different heights (in cm)and the height of the bounce is recorded (in cm).The regression analysis gives the model $\hat{\text { bounce }} = - 0.2 + 0.75$ drop.A golf ball dropped from 61 cm bounced a height whose residual is -1.8 cm.What is the bounce height?
A)1.8 cm
B)59.45 cm
C)59.2 cm
D)47.35 cm
E)43.75 cm

The predicted bounce height is calculated as $-0.2 + 0.75 \times 61 = 45.55$ cm. The actual bounce height is the predicted height plus the residual: $45.55 - 1.8 = 43.75$ cm.
