For the sampling distribution of sample means, what is the relationship between the population mean and the mean of all possible sample means of size 25?? They are different by one standard error of the mean.They are not equal.They are both normally distributed.They are equal. 相关知识点: ...
The population mean for random numbers 1-7 is 4, and the distribution of sample means is normal and centered on the population mean. Just as it is unlikely that a fair coin will come up tails nearly all the time or heads nearly all the time, it is unlikely that the great majority of...

1.What is the Standard error of mean? The standard error of the mean is designated as: σM. It is the standard deviation of the sampling distribution of the mean. The formula for the standard error of the mean is:where σ is the standard deviation of the original distribution and N is...
Each sample has its own sample mean, and the distribution of the sample means is known as the sample distribution. Special Considerations The number of observations in a population, the number of observations in a sample, and the procedure used to draw the sample sets determine the variability ...
