Document Summary
The chamber of commerce in a canadian city has conducted an evaluation of 300 restaurants in its metropolitan area. Each restaurant received a rating on a 3-point scale on typical meal price (1 least expensive to 3 most expensive) and quality (1 lowest quality to 3 greatest quality). A crosstabulation of the rating data is shown below. Forty-two of the restaurants received a rating of 1 on quality and 1 on meal price. Thirty-nine of the restaurants received a rating of 1 on quality and 2 on meal price, and so on. Forty-eight received the highest rating on both quality and meal price. 300: develop a bivariate probability distribution for quality and meal price of a randomly selected restaurant in this canadian city. Let x = quality rating and y = meal-price rating: compute the expected value and variance for quality rating x, compute the expected value and variance for meal price rating y, the var(x+y) = 1. 6691.
