A random sample of size 4 is selected from population A which has a standard deviation of 6 and a
random sample of size 16 is selected from population B which has a standard deviation of 10. The
standard error of the mean for the sample from population A is smaller than that for the sample from
population

Question

Quizplus · Accepted Answer

The standard error of the mean for a sample is inversely proportional to the sample size and proportional to the standard deviation of the population. Since the sample from population B is larger in size, its standard error of the mean will be smaller compared to that of the sample from population A.
