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 that someone wants to predict the cost of dinner at a restaurant in a city based on the Zagat food quality ratings. If 10 restaurants in a city are sampled and the regression output is given below, what can we conclude about the slope of food quality?Question 11 options: 1) The slope is equal to 0. 2) The slope is 1.7 and therefore differs from 0. 3) Not enough evidence was found to conclude the slope differs significantly from 0. 4) Since we are not given the dataset, we do not have enough information to determine if the slope differs from 0. 5) The slope significantly differs from 0.
