let z be the distance in miles from the house to the nearest fire station and let y be the damage to the house in thousands of dollars. The following table lists the given data for the five houses and additional calculations from the last assignment. 3 8 11 18 31 30 19 2-4 -3.4 1.6 -3.4 4.6 0.6 y-y -6.2 6.8 -1.2 5.8 --5.2 (x-x)(y-7) 21.08 10.88 4.08 26.68 -3.12 (x-x)² 11.56 2.56 11.56 21.16 0.36 (y-7)² 38.44 46.24 1.44 33.64 27.04 1. Use this data to find the least squares line for the points represented by the pairs (x.y). (Write the slope by and intercept bo of that line to two decimal places.) 2. Plot the points (x, y) below (that is, draw a scatterplot for this data set), and sketch the least squares line that you found in Question 1. Be sure to label values along the r and y axes appropriately. (Hint: Plotting the points (7,5) and the point (0, bo) might help you draw this line more accurately.) let z be the distance in miles from the house to the nearest fire station and let y be the damage to the house in thousands of dollars.
