Predict the mean cost per person for a restaurant with a summated rating of 60. Y;=$45.85 per person(Round to the nearest cent as needed.) e.What should you tell the owner of a group of restaurants in this geographical area about the relationship between the summated rating and the cost of a meal? OA.As expected,the lower the summated rating of the restaurant,the higher the restaurant can charge per meal. O B.As expected,the higher the summated rating of the restaurant,the less the restaurant can charge per meal. OC.As expected,the summated rating of the restaurant is not associated with what the restaurant can charge per meal. O D.As expected,the higher the summated rating of the restaurant,the higher the restaurant can charge per meal.

Assuming a linear relationship,use the least-squares method to compute the regression coefficients bo and b1. b0=-39.35andb1=1.42 (Round to two decimal places as needed. c.Interpret the meaning of the Y-intercept,bo,and the slope,b1.Choose the correct answer below. O A.The Y-intercept,bo,implies that if the summated rating of a restaurant is zero,the cost per meal is equal to bo,in dollars.The slope,b1,implies that for each increase of 1 in the summated rating,the cost per person is expected to decrease by b1,in dollars. B.The Y-intercept,bo,implies that if the summated rating of a restaurant is zero,the cost per meal is equal to bo,in dollars.The slope,b1,implies that for each increase of 1dollar in the cost per person,the summated rating is expected to increase by b1. OC.A practical interpretation of the Y-intercept bo is not meaningful because no operating restaurant is likely to have a rating of zero.The slope b1 implies that for each increase of 1 in the summated rating,the cost per person is expected to increase by the value of b1,in dollars. OD.The Y-intercept,bo,implies that if the summated rating of a restaurant is zero,the cost per person is bo,in dollars.The slope,b,implies the average cost per person is b dollars.

In a restaurant, the cost of providing a particular typeof food is partly constant and partly inverselyproportional to the number of people. If the cost perhead for 100people is 30k and the cost for 40 people is60k, find the cost for 50people*15k4520k50k40k

a.Construct a 95%confidence interval estimate of the mean cost of a meal for restaurants that have a summated rating of 51. 19.857≤Y1X=×1≤26.923 (Type integers or decimals.Round to three decimal places as needed.Use ascending order.) b.Construct a 95%prediction interval of the cost of a meal for an individual restaurant that has a summated rating of 51. 4.498≤Yx=51≤42.283 (Type integers or decimals.Round to three decimal places as needed.Use ascending order.) c.Explain the differences in the results from (a)and(b).Choose the correct answer below. OA.Since there is more variation in estimating a mean value than in predicting an individual value,the confidence interval is narrower than the prediction interval,holding everything else fixed. B.Since there is more variation in estimating a mean value than in predicting an individual value,the confidence interval is wider than the prediction interval,holding everything else fixed. O C.Since there is more variation in predicting an individual value than in estimating a mean value,the prediction interval is wider than the confidence interval,holding everything else fixed. OD.Since there is more variation in predicting an individual value than in estimating a mean value,the prediction interval is narrower than the confidence interval,holding everything else fixed.

What would the minimum suggested selling price be for a salad bar that averaged 100 guests per day, spent a total of $285 on food each day and targeted a 30% food cost?
