Question 1 7 pts 1. What is the \( y \)-intercept (A) value? Note: Round off your answer to the nearest tenths. Example: 12.3 Follow strictly the answer format for your answer to be considered correct. Otherwise, incorrect. Unit 4: Mathematics as a Tool - Data Management 4.7 Regression Analysis PROBLEM: The data in the table represent the membership at a university Mathematics Club during the past 5 years. Find the regression equation and predict the number of members at year 12 . \begin{tabular}{|c|c|} \hline \begin{tabular}{c} No. of \\ Years \\ \( \mathbf{( X )} \) \end{tabular} & \begin{tabular}{c} No. of \\ Members \\ \( (\mathbf{Y}) \) \end{tabular} \\ \hline 1 & 25 \\ \hline 2 & 30 \\ \hline 3 & 32 \\ \hline 4 & 45 \\ \hline 5 & 50 \\ \hline \end{tabular}
