The sales manager of a large company selected a random sample of n = 10 salespeople and determined for each one the values of x = years of sales experience and y = annual sales (in thousands of dollars). a scatterplot of the resulting (x, y) pairs showed a linear pattern. (a) suppose that the sample correlation coefficient is r = 0.75 and that the average annual sales is y = 100. if a particular salesperson is 2 standard deviations above the mean in terms of experience, what would you predict for that person's annual sales? since the value for experience is 2 standard deviations above the mean experience, you can predict annual sales will be 2 standard deviations above the mean annual sales
