Consider the following time series.
able[[t,1,2,3,4,5,6,7],[Y_(t),121,108,99,94,93,90,88]]
(a) Construct a time series plot.
(i) O
What type of pattern exists in the data? ◻
(b) Develop the linear trend equation for this time series. (Round your numerical values to two decimal places.)
T_(t)=
◻
(c) What is the forecast for t=8 ? (Round your answer to one decimal place.)
◻
What type of pattern exists in the data? O The time series plot shows a linear trend. The time series plot shows a horizontal pattern The time series plot shows a nonlinear trend. O The time series plot shows a seasonal pattern.
(b) Develop the linear trend equation for this time series.(Round your numerical values to two decimal places. t 126.5-5.5t X
(c)What is the forecast for t = 8? (Round your answer to one decimal place.)
