An 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). x 17 34 50 28 50 25 y 2 4 5 5 9 3 find the value of the sample correlation coefficient r. (Round your value for r to four decimal places.) a) r = Find x, and y. (Round your answers to four decimal places.) b) x= c) y=
