8. Find the standard deviation. (Enter an exact number as an integer, fraction, or decimal.)
| x | P(x) |
x*P(x)
|
(x − ?)2P(x)
|
|---|---|---|---|
| 3 | 0.1 |
3(0.1) = 0.3
|
(3 − 6.4)2(0.1) = 1.156
|
| 5 | 0.3 |
5(0.3) = 1.5
|
(5 − 6.4)2(0.3) = 0.588
|
| 7 | 0.4 |
7(0.4) = 2.8
|
(7 − 6.4)2(0.4) = 0.144
|
| 9 | 0.2 |
9(0.2) = 1.8
|
(9 − 6.4)2(0.2) = 1.352
