few years. The annual revenue, in millions of dollars, for the previous 10 years is shown. \begin{tabular}{|c|c|} \hline Year & Revenue \\ \hline 1 & 8.63 \\ \hline 2 & 10.74 \\ \hline 3 & 13.08 \\ \hline 4 & 14.11 \\ \hline 5 & 16.41 \\ \hline 6 & 17.31 \\ \hline 7 & 18.27 \\ \hline 8 & 18.45 \\ \hline 9 & 18.30 \\ \hline 10 & 18.53 \\ \hline \end{tabular} (a) Cons Comment on the appropriateness of a linear trend. The time series plot shows that a curvilinear trend may be more appropriate. \( \smile \) The time series plot shows that neither a linear nor a curvilinear trend is appropriate. The time series plot shows that a linear trend is most appropriate. (b) Using statistical software, develop a quadratic trend equation that can be used to forecast revenue (in millions of dollars). (Round your numerical values to three decimal places.) \( T_{t}= \) (b) Using statistical software, develop a quadratic trend equation that can be used to forecast revenue (in millions of dollars). (Round your numerical values to three decimal places.) \[ T_{t}= \] (c) Using the trend equation developed in part (b), forecast revenue (in millions of dollars) in year 11. (Round your answer to two decimal places.) \$ million
