StatisticsQ&A LibraryAn economist is studying the job market in Denver area neighborhoods. Let x represent the total number of jobs in a given neighborhood, and let y represent the number of entry-level jobs in the same neighborhood. A sample of six Denver neighborhoods gave the following information (units in hundreds of jobs). 13 30 52 28 50 25 y 3 4 5 3 Verify the given sums Ex, Ey, Ex², Ey2, Exy, and the value of the sample correlation coefficient r. (Round your value for r to four decimal places.) Σχ = Ey = Ex? %3D Ey? = Σχy - r = Find x, and y. Then find the equation of the least-squares line ŷ = a + bx. (Round your answers to four decimal places.) y = Find the value of the coefficient of determination r. What percentage of the variation in y can be explained by the corresponding variation in x and the least-squares line? What percentage is unexplained? (Round your answer for r to four decimal places. Round your answers for the percentages to two decimal place.) explained % unexplained % For a neighborhood with x = 31 hundred jobs, how many are predicted to be entry level jobs?
