1. 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.)

2. For a neighborhood with x = 12% change in population in the past few years, predict the change in the crime rate (per 1000 residents). (Round your answer to one decimal place.)
