Mean is $\overline{x} =15.4$ and standard deviation is 3.02581485

Step-by-step explanation:

Given mean is 19.4 and standard deviation is 5.8

the given data are: - 12, 15, 17, 20, 13, 11, 18, 19, 15, 14

Mean of given data is calculated as :-

$\overline{x} =\frac{1}{n}\sum_{i=1}^{n}x$

$\overline{x} =\frac{12+15+17+20+13+11+18+19+15+14}{10}$

$\overline{x} =\frac{154}{10}$

$\overline{x} =15.4$

Mean is $\overline{x} =15.4$

standard deviation is calculated as :-

$s=\sqrt{\frac{1}{n-1}\sum_{i=1}^{n}(x-\overline{x})^{2}$

the sum of $(x-\overline{x})^{2}$ is performed in figure-1

$s=\sqrt{\frac{1}{10-1}\sum_{i=1}^{n}(\frac{412}{5})$

$s=\sqrt{\frac{1}{9}\times\frac{412}{5}$

$s=\sqrt{(\frac{412}{45})$

s=3.02581485

standard deviation is 3.02581485

For a population, the mean is 19.4 and the standard deviation is 5.8. compare the mean and standard
