The scores of the athletes are 32,45,33,22,50,48. Find the variance.

Grace [21]

Answer:

Step-by-step explanation:

First, find the mean ; (32+45+33+22+50+48) / 6 = 230/6

Mean = 38.33

Variance = $\frac{SUM(X-meanX)^{2} }{n-1}$

n = sample size

Variance = $\frac{(32-38.33)^{2} +(45-38.33)^{2}+(33-38.33)^{2} +(22-38.33)^{2}+(50-38.33)^{2}+(48-38.33)^{2} }{5}$

Variance = $\frac{(44.4889 +40.0689 +28.4089 + 266.6689 +136.1889 +93.5089)}{5}$

= $\frac{609.3334}{5}$

= 121.8667

Therefore, variance = 121.87

Answer: -5 and -7

Step-by-step explanation:

| $\frac{x}{2}$ +3| = $\frac{1}{2}$

It has 2 cases

the first case ;

$\frac{x}{2}$ + 3 = $\frac{1}{2}$

$\frac{x}{2}$ = $\frac{-5}{2}$

x = -5

the second case;

$\frac{x}{2}$ + 3 = $\frac{-1}{2}$

$\frac{x}{2}$ = $\frac{-7}{2}$

x = -7
