Homework Answers
Correct answer is Option B.
An exponentially smoothed moving average gives more
weight to more recent observations. An exponentially
smoothed moving average is a weighted moving average. In
exponentially smoothed moving average, the weight factors are
powers of S, the smoothing constant.
