Answer:
s = $13,014.22
Explanation:
Sample values: $40,632, $35,554, $42,192, $33,432, $69,479 and $43,589
Sample size = 6
The standard deviation of a sample (s) is given by:
[tex]s=\sqrt{\frac{\sum(x_i-X)^2}{n-1}}[/tex]
Where X is the sample mean, n is the sample size, and xi is each value in the sample.
The sample mean is given by:
[tex]X=\frac{\$40,632 +\$35,554+\$42,192 +\$33,432 +\$69,479 +\$43,589}{6} \\X=\$44,146.33[/tex]
The standard deviation is:
[tex]s=\sqrt{\frac{\sum(x_i-\$44,146.33)^2}{6-1}}\\s=\$13,014.22[/tex]
