For a population, the mean is 19.4 and the standard deviation is 5.8. compare the mean and standard deviation of the following random samples to the population parameters.

12, 15, 17, 20, 13, 11, 18, 19, 15, 14

Mean is 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 :-

Mean is

standard deviation is calculated as :-

the sum of is performed in figure-1

standard deviation is 3.02581485
