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.

Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.
