0.90 and I think .9 is another I'm not sure but I tried
1. 81.72
2. 10.37
3. 81.72 + 10.37 = 92.09 81.72 - 10.37 = 71.35
4. 81.72 + 2(10.37)= 102.46 81.72 - 2(10.37) = 60.98
5. 81.72 + 3(10.37) = 112.83 81.72-3(10.37) = 50.61
6. no
7. It is not bell-shaped
8. P(>=90) = 15/50 = 3/10 = 30%; 2nd way??
9. 5 = 68, 12 = 72, 24 = 82, 35 = 89, 43 = 92
10. 80.6
