a.

Expert Solution

To determine

Find the amount of profit for a restaurant with the given conditions.

Answer to Problem 1SR

The amount of profit for a restaurant with the given conditions is $389,500.

Explanation of Solution

Calculation:

Multiple linear regression model:

A multiple linear regression model is given as y^=a+b1x1+b2x2+b3x3+...+bkxk where y is the response or dependent variable, and x1,x2,...,xk are the k quantitative independent variables where k is a positive integer.

Here, a is the intercept term of the regression model, that is, the value of predicted value of y when X’s are 0 and bi’s are the slopes, that is, the amount of change of the predicted value of y for one unit increase in xi when all other independent variables are constant.

In the given problem the predicted dependent variable y is the amount of profit in $1,000. The number of parking space near the restaurant, the number of hours the restaurant is opened per week, the distance from the landmark in Beach M, the number of servers and the number of years the current owner operated the restaurant are defined as x1,x2,x3,x4 and x5, respectively.

Hence, using the given information the regression equation is y^=2.50+3x1+4x2−3x3+0.20x4+x5.

Thus, the amount of profit for a restaurant with 40 parking spaces which is open 72 hours per week, 10 mile from a landmark of Beach M with 20 servers and has been operated by the current owner for 5 years, is calculated as follows:

y^=2.50+3(40)+4(72)−3(10)+0.20(20)+5=2.50+120+288−30+4+5=389.5

Therefore, the amount of profit for a restaurant with the given conditions is $389,500.

b.

Expert Solution

To determine

Explain the values of b2 and b3 in the multiple regression equation.

Explanation of Solution

It is clear that, the value b2 is 4 which is the coefficient of x2, the number of hours the restaurant is opened per week.

Hence, it can be concluded that if the restaurant is opened one more hour per week, then the amount of profit for the restaurant would be increased by $4,000, when all the other factors are constant.

It is clear that, the value b3 is –3 which is the coefficient of x3, the distance from the landmark in Beach M.

Hence, it can be concluded that if the restaurant is opened one more mile away from the landmark of Beach M, then the amount of profit for the restaurant would be decreased by $3,000, when all the other factors are constant.
