1 ### Regression Analysis in Hotel PricingDifferent hotels in a certain area are randomly selected, and their ratings and prices were obtained online. Using technology, with \( x \) representing the ratings and \( y \) representing price, we find that the regression equation has a slope of 130 and a y-intercept of -350. Complete parts (a) and (b) below.#### a. What is the equation of the regression line?Select the correct choice below and fill in the answer boxes to complete your choice.- **A.** \(\hat{y} = [ \quad ] + ( [ \quad ] ) x \)- **B.** \(\hat{y} = [ \quad ] - ( [ \quad ] ) x \)- **C.** \(\hat{y} = [ \quad ] + ( [ \quad ] ) x \)- **D.** \(\hat{y} = [ \quad ] - ( [ \quad ] ) x \)#### b. What does the symbol \(\hat{y}\) represent?- **A.** The symbol \(\hat{y}\) represents the expected price when the hotel's rating is 0.- **B.** The symbol \(\hat{y}\) represents the average price of hotels in the area.- **C.** The symbol \(\hat{y}\) represents the predicted value of price.- **D.** The symbol \(\hat{y}\) represents the amount that price increases with a 1-point increase in rating.### Explanation and Solution:#### Regression Line EquationFor a regression equation of the form \(\hat{y} = mx + b\), where \(m\) represents the slope and \(b\) represents the y-intercept:- Given the slope (\(m\)) is 130 and the y-intercept (\(b\)) is -350.- The correct equation is: \[\hat{y} = -350 + 130x\]Thus, the correct answer for part (a) is:\[ \mathbf{A.} \ \hat{y} = -350 + (130) x \]#### Interpretation of \(\hat{y}\)The symbol \(\hat{y}\) in regression analysis typically represents the predicted value of the dependent variable based on the regression equation and the corresponding value of the independent variable.

Given:Slope=130y-Intercept=-350
