1. Based on data collected over several sessions, a statistically minded trainer of office typists modeled the linzoom in
between the number of hours of training a typist receives and the typist's speed (in words per minute) with the equauon
speed = 10.3 +5.4(hour). After some training, one of the typists was told that the speed he attained had a residual of 4.2
words per minute. How should he interpret this?
Choose the correct answer below.
1
A. He cannot interpret his residual without also knowing the correlation.
B. He cannot interpret his residual without also knowing the size of other people's residuals.
C. He types slower than the model predicted, given the amount of time he spent training.
D. He types faster than the model predicted, given the amount of time he spent training.
