Tutor description

An agent for a residential 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 in square footage. Data was gathered from a sample of 25 apartments in a particular residential neighborhood and an ordinary least squares regression was run. The sample rents range from \$875 to \$2,300 and the sample sizes range from 800 to 1,985 square feet. The output from the Excel regression is provided in the attachment. 1. Write out the regression equation (with the calculated coefficient estimates). 2. Interpret the meaning of b0 and b1 in this problem 3. What is the coefficient of determination (r2) and what does it tell you about the model? 4.
