Answer to Question 1

c
RATIONALE: To use moving averages to forecast a time series, we must first select the order k, or the number of time series values to be included in the moving average. If only the most recent values of the time series are considered relevant, a small value of k is preferred. If a greater number of past values are considered relevant, then we generally opt for a larger value of k.

Answer to Question 2

d
RATIONALE: One type of helpful chart for examining data with more than two variables is the parallel-coordinates plot, which includes a different vertical axis for each variable.
