(a) Determine the estimated multiple linear regression equation that can be used to predict the overall score given the score for comfort, amenities, and in-house dining. Let \( x_{1} \) represent Comfort. Let \( \times_{2} \) represent Amenities. Let \( x 3 \) represent in-House Dining. \( \hat{y}=x_{1}+x_{2}+x_{3} \) (b) Use the \( t \) test to detelmine the significance of each independent variable. What is the conclusion for each test at the \( 0.01 \) level of significance? If your answer is zero, enter " 0 ". The \( p \)-value associated with the estimated regression parameter \( b_{1} \) is We conclude that there the \( 0.01 \) level of significance when controlling for score at the \( 0.01 \) level of significance when controlling fol (c) Remove all independent variables that are not significant at the \( 0.01 \) level of significance from the estimated regression equation. What is your recommended estimated regression equation? Enter a coefficient of zero for any independent variable you chose to remove. \( \hat{y}= \)
