Different 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 135 and a y-intercept of - 387. 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. O A. ŷ= O B. y= OC. y=+ O D. ŷ =• (Dâ b. What does the symbol y represent? O A. The symbol y represents the predicted value of price. O B. The symbol y represents the expected price when the hotel's rating is 0. OC. The symbol y represents the amount that price increases with a 1-point increase in rating. O D. The symbol y represents the average price of hotels in the area.

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
