Each restaurant received a rating on a 3-point scale (1 lowest to 3 highest) on typical meal price and quality (1 lowest to 3 highest). A cross tabulation of the rating data is shown below. Forty-two of the restaurants received a rating of 1 on quality and 1 on meal price, 39 of the restaurants received a rating of 1 on quality and 2 on meal price and so on. Forty-eight of the restaurants received the highest rating of 3 on both quality and meal prices (see the cross tabular below).
