Question

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.

25, 32, 16, 12, 11, 38, 22, 21, 19, 20

anonymous · Answer

The mean is lower than the population and the standard deviation is greater, which means that the data values in the sample are more spread out than the population.

	
The mean is lower than the population and the standard deviation is less, which means that the data values in the sample are more spread out than the population.

	
The mean is higher than the population and the standard deviation is less, which means that the data values in the sample are more spread out than the population.
