(c) Find the sample correlation coefficient r and the coefficient of determination. (Round your answers to three decimal places.) What percentage of variation in y is explained by the least-squares model? (Round your answer to one decimal place.) % (d) For a neighborhood with x = 10% change in population in the past few years, predict the change in the crime rate (per 1000 residents).

MY NOTES ASK YOUR TEACHER 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. 30 11 177 17 35 132 127 69 53 LO USE SALT Ex = 73; Ey = 593; Ex2 = 1,399; Ey2 = 73,677; Exy = 9,792 (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 three decimal places.) X = y = b = (b) Draw a scatter diagram for the data.
