An agent for a property management company 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 25 apartments rent in a particular college rental neighborhood was selected, and the information collected revealed the following (see attached image)

Construct a 95% confidence interval estimate of the population slope B1.  Don’t forget to interpret the interval.  Always declare the meaning of B1 when we test or estimate the slope parameter…use b1 ± t α/2,n-2 (Sb1).

Determine a 95% interval estimate for the average rent of apartments with 1000 square feet.  Determine ŷ1000 and interpret the interval estimate for the average rent completely.
