A magazine collected the ratings for food, decor, service and the cost per person for a sample of 96 restaurants. They combined the ratings to create a summated rating and used that to predict the cost of a restaurant meal. The data are modeled by Y, = - 30.871 +0.9349X,, where X, is the summated ratings and Y, is meal cost. For these data, Syx = 8.575, X= 61.02, and h, = 0.027122 when X= 52. Complete parts (a) through (c). a. Construct a 90% confidence interval estimate of the mean cost of a meal for restaurants that have a summated rating of 52. (Type integers or decimals. Round to three decimal places as needed. Use ascending order.)
