A population has a mean of 50 and a standard deviation of 8. If samples of size N = 16 are randomly drawn from this population, then the standard error will be equal to.
A)1.0
B)2.0
C)8.0
D)0.5

The formula for calculating standard error is standard deviation divided by the square root of the sample size: SE = σ/√n. 
Plugging in the values, we get SE = 8/√16 = 8/4 = 2.0. Thus, the standard error will be 2.0 in this case. So, the correct choice is B.
