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
11. no
12. The population mean includes all of the data values and the sample mean only includes the 5 data values.

Answer:
<h2>
aₙ = -3n + 8</h2>
Step-by-step explanation:
The nth term of an arithmetic sequence: aₙ = a₁ + d(n - 1)
{d = common difference}
a₁ = 5
a₄ = 5 + d(4 - 1)
-4 = 5 + 3d
-4 - 5 = 3d
3d = -9
d = -3
Therefore;
aₙ = 5 + (-3)(n - 1)
aₙ = -3n + 8
Check: a₁₀ = 5 + (-3)(10 - 1) = 5 - 27 = - 22
