Answer:

Standard Deviation = 3.22

Variance = 10.36

Step-by-step explanation:

x          P(x)           x × P(x)              x²             x² × P(x)

19         0.20           3.8                  361               72.2

10         0.20             2                   100                20

11          0.30           3.3                   121                36.3

12         0.20           2.4                   144               28.8

13          0.10            1.3                   169                16.9

____________________________________________

                            12.8                                         174.2            => Total

<em><u>Mean Formula</u></em>

\mu_x = \sum(x \times P(x)) = 12.8

\mu_x^2 = 163.84

<em><u>Variance Formula</u></em>

\sigma _x^2 = \sum[x^2 \times P(x)] - \mu_x^2      

   = 174.2- 163.84\\\\=10.36

<em><u>Standard Deviation Formula</u></em>

Standard\ deviation, \ \sigma_x = \sqrt{Variance}

                                   =\sqrt{10.36}\\\\=3.218
