Use the given data to find the equation of the regression line. Round the final values to three significant digits, if necessary. Two different tests are designed to measure employee productivity and dexterity. Several employees are randomly selected and tested with these results. Productivity (x) | 23 | 25 | 28 | 21 | 21 | 25 | 26 | 30 | 34 | 36 Dexterity (y) | 49 | 53 | 59 | 42 | 47 | 53 | 55 | 63 | 67 | 75 ? = 2.36 + 2.03x ? = 10.7 + 1.53x ? = 75.3 - 0.329x ? = 5.05 + 1.91x

Managers rate employees according to job performance and attitude. The results for several randomly selected employees are given below. Performance (x) / 2 / 10 / 4 / 6 / 9 / 5 / 1 / 7 / 8 / 3 Attitude (y) / 2 / 1 / 5 / 7 / 4 / 1 / 3 / 9 / 5 / 3 Use the given data to find the equation of the regression line. Round the final values to three significant digits, if necessary. (Enter the slope for full credit.)
