An evaluation of 300 restaurant was conducted. Each restaurant recieved a rating on a 3 point scale on typical meal price (1 least expensive to most expensive) and quality (1 lowest to 3 greatest quality). A cross tabulation on the rating data is shown. Forty two of the restaurants received a rating of 1 on quality and 1 on meal price, 39 of the restaurants recieved the highest rating of 3 on both quality and meal price. A bivariate probability distribution for quality and meal price of a randomly selected restaurant is provided. x is the wuality rating and y is the meal price. Meal price (y) 1 2 3 Total Quality (x) 1 0.14 0.13 0.01 0.28 2 0.11 0.21 0.18 0.5 3 0.01 0.05
