Random samples of size 36 each are taken from a large population whose mean is 120 and standard deviation is 39.The standard error of the sampling distribution of sample mean is:
A)39
B)6.5
C)15.6
D)24.5

Question

Quizplus · Accepted Answer

The standard error of the mean (SE) can be calculated using the formula: 
SE = standard deviation / square root of sample size 
SE = 39 / square root of 36 
SE = 39 / 6 
SE = 6.5 
Therefore, the standard error of the sampling distribution of sample mean is 6.5.
