If all possible samples of size n are drawn from a large population with a mean of 20 and a standard deviation of 5, then the standard error of the sample mean equals 1.0 only for samples of size:
A) 15
B) 20
C) 25
D) 30
E) 35
Standard Error
The standard deviation of the sampling distribution of a statistic, especially of the mean.
Sample Mean
The average value calculated from a sample of observations from a larger population.
- Gain an understanding of the principle of standard error and its critical role in illustrating the variability among sample statistics.
- Acquire knowledge about the effects of sample size on the distribution of samples, including changes to the standard error and the distribution's configuration.
