(a)
Construct a time series plot.
A time series plot contains a series of 24 points connected by line segments. The horizontal axis ranges from 0 to 25 and is labeled: Period. The vertical axis ranges from 0 to 10 and is labeled: Budget ($ billions). The first point is at approximately (1, 8.8). The rest are plotted from left to right at regular increments of 1 period in a downward, diagonal direction. The last point is at approximately (24, 3.0). Consecutive points are close together with little scatter.

The vertical axis ranges from 0 to 10 and is labeled: Budget ($ billions). The first point is at approximately (1, 6.8). The rest are plotted from left to right at regular increments of 1 period in a downward, diagonal direction. The last point is at approximately (24, 1.0). Consecutive points are close together with little scatter.

The vertical axis ranges from 0 to 10 and is labeled: Budget ($ billions). The first point is at approximately (1, 2.0). The rest are plotted from left to right at regular increments of 1 period in an upward, diagonal direction. The last point is at approximately (24, 7.8). Consecutive points are close together with little scatter.

What type of pattern exists in the data?
The time series plot shows a horizontal pattern.The time series plot shows a linear trend.     The time series plot shows a seasonal pattern.The time series plot shows a nonlinear trend.
(b)
Develop a linear trend equation for this time series to forecast the budget (in billions of dollars). (Round your numerical values to three decimal places.)
Tt = 
 
 
 
(c)
What is the forecast (in billions of dollars) for period 25? (Round your answer to two decimal places.)
