where Y represents hourly worker compensation in dollars) and X represents hourly production of microchips (e.g., 50.5=50.5 chips): 1. State your hypothesis. 2. What are your cases/unit of analysis? 3. Calculate the correlation coefficient. Interpret the correlation coefficient/results with respect to the hypothesis. 4. Is your hypothesis supported? How do you know? 51.4 13.7 53.2 14.2 55.7 14.8 57.9 15.4 60.6 16.2 62.7 16.8 65.2 17.9 66.6 18.9 68.9 20.5 69.2 21.9 70.6 23.6 73.6 25.1 76.0 26.7 78.4 29.0 77.1 31.8 79.8 35.1 82.5 38.2 84.0 41.2 849 44.9 84.5 49.2 84.2 54.5 85.8 59.6 85.3 64.1 88.0 66.8 90.2 69.7 91.7 73.1 94.1 768 94.0 79.8 94.7 83.6 95.5 85.9 96.1 90.8 96.7 95.1 100.0 100.0 100.1 102.5 100.7 104.4 101.0 106.8 103.7 110,7 105.4 114.9
