Zagat restaurant guides publish ratings of restaurants for many large cities around the world. The restaurants are rated on a 0 to 30 point scale based on quality of food, decor, service, and cost. Suppose the regression equation that predicts the cost of dinner using the rating of the quality of food for the restaurants in a particular city is (cost of dinner) = 3.477*(food quality) + 2.955. Interpret the slope.

Question 8 options:

1)When cost of dinner increases by 1 dollar, food quality increases by 3.477 points.

2)When cost of dinner increases by 1 dollar, food quality increases by 2.955 points.

3)When food quality increases by 1 point, cost of dinner increases by 2.955 dollars.

4)When food quality increases by 1 point, cost of dinner increases by 3.477 dollars.

5)We are not given the dataset, so we cannot make an interpretation.
