An agent for a residential real estate company in a suburb located outside a major city has the business objective of developing more accurate estimates of the monthly rental cost for apartments. Toward the? goal, the agent would like to use the size of an? apartment, as defined by square footage to predict the monthly rental cost. The agent selects a sample of 8? one-bedroom apartments and the data are shown. Complete parts? (a) through? (f).
Monthly Rent ($) Size (Square Feet)
975 800
1,500 1,300
800 900
1,600 1,250
1,950 1,800
950 750
1,700 1,350
1,250 1,100
a. Construct a scatter plot. Choose the correct graph below.
A.A scatter plot has a horizontal axis labeled Size (in square feet) from 0 to 2000 in increments of 400 and a vertical axis labeled Rent ($) from 0 to 2000 in increments of 400. A series of plotted points are clustered around a line that rises from left to right passing through the points (1200,1400) and (1600,1800). All coordinates are approximate.
Your answer is correct.
b. Use the? least-squares method to determine the regression coefficients b0 and b 1.
b0=___________?(Round to one decimal place as? needed.)
