Question

c. How useful is this model for predicting the monthly rent?

d. What other variables might explain the variation in monthly rent?

An agent for a real estate company in a large city would like to be able to predict the monthly rental cost for apartments, based on the size of the apartment, as defined by square footage. A sample of eight apartments in a neighborhood was selected, and the information gathered revealed the data shown below. For these data, the regression coefficients are bo 294.0733 and b10.9073. Complete parts (a) through (d) Monthly Rent (S) 950 1,500 800 1,500 1,950 900 1,800 1,300 Size (Square Feet 850 1,300 950 1,100 2,000 650 1,300 1,050 a. Determine the coefficient of determination, r', and interpret its meaning (Round to four decimal places as needed.)
