This question refers to Activity 7-2 in the workbook. It won't make sense unless you follow along in the workbook. Even though it doesn't ask about short answer questions you should still answer those in your workbook. PART 1 Mean Annual Temperature: 51.3, 49.9, 50, 49.2, 48.5, 47.8, 47.3, 45.1, 46.3, 42.1, 44.2, 43.5, 42.3, 40.2, 31.8, 34 Mortality Index: 102.5, 104.5, 100.4, 95.9, 87, 95, 88.6, 89.2, 78.9, 84.6, 81.7, 72.2, 65.1, 68.1, 67.3, 52.5 1.
