The following data represent the amount of soft drink in a sample of 50 consecutively filled 2-liter bottles. The results are listed horizontally in the order of being filled:

a. Construct a time series plot for the amount of soft drink on the Y axis and the bottle number on the X axis
c. If you had to make a prediction about the amount of soft drink filled in the next bottle, what would you predict?
d. Based on the results of (a) through (c), explain why it is important to construct a time-series plot and not just a histogram, as was done in Problem 2.43 on page 69.
