Question
The standard error of the mean is
The standard deviation of the sampling distribution of the mean is called the
As the sample size increases the standard error of the mean increases
If the population distribution is unknown, in most cases the sampling distribution of the mean can be approximated by the normal distribution if the samples contain at least 30 observations
As the sample size increases, the effect of an extreme value on the sample mean become smaller
A. True
As the sample size increases, the variation of the sample mean from the population mean becomes larger and larger
A. less than the standard deviation of the population B. decreases as the sample size increases C. measures the variability of the mean from the sample to sample D. all of the aboveExplanation / Answer
