Let x be a random variable representing percentage change in neighborhood population in the past few years, and let y be a random variable representing crime rate (crimes per 1000 population). A random sample of six Denver neighborhoods gave the following information. x 31 1 11 17 7 6 y 176 37 132 127 69 53 In this setting we have Σx = 73, Σy = 594, Σx2 = 1457, Σy2 = 73,468, and Σxy = 9905. (a) Find x, y, b, and the equation of the least-squares line. (Round your answers for x and y to two decimal places. Round your least-squares estimates to four decimal places.) x =  y =  b =  ŷ =  +  x
