Different hotels in a certain area are randomly selected, and their ratings and prices were obtained cnline. Using technology, with x representing the ratings and y representing price. we nd that the regression equation has a slope of 130 and a yiintercept of 4167. Complete parts (a) and (in) below. a. What is the equation of the regression line?. Select the correct choice below and ll in the answer boxes to complete your choice. 05- y: +( )3: ea. ,7: + ; 06- ;= + x Olly: +( )2 b. What does the symbol Iy' represent? O A. The symbol represents the average price of hotels in the area. 0 B. The symbol 5? represents the amount that price increases with a 1-point increase in rating. 0 c. The symbol 5? represents the predicted value at price. O D. The symbol 3? represents the expected price when the hotel's rating is D. Suppose IQ scores were obtained for 20 randomly selected sets of twins. The 20 pairs of measurements yield x = 95.95, y = 96.65, r =0.870, P-value = 0.000, and y = 2.4 + 0.98x, where x represents the IQ score of the twin born second. Find the best predicted value of y given that the twin born second has an IQ of 102? Use a significance level of 0.05. Click the icon to view the critical values of the Pearson correlation coefficient r. The best predicted value of y is . (Round to two decimal places as needed.)
