A county real estate appraiser wants to develop a statistical model to predict the appraised value of houses in a section of the county called East Meadow. One of the many variables thought to be an important predictor of appraised value is the total number of rooms in the house. Consequently the appraiser decided to fit the simple linear regression model, ^y=β0+β1x, where y= the appraised value of the house (in thousands of dollars) and x= the number of rooms. Using data collected for a sample of n = 74 houses in East Meadow, the following results were obtained:¯y=74.80+24.93xRange of the x-values: 5 - 11Range of the y-values: 160 - 300Give a practical interpretation of the estimate of the slope and the y-intercept of the least-squares line.
