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