Consider a large population with a mean of 150 and a standard deviation of 27. A random sample of size 36 is taken from this population. The standard error of the sampling distribution of sample mean is equal to:
A) 4.17
B) 4.50
C) 5.20
D) 5.56
E) 6.00

The formula for the standard error is:

SE = σ/√n

where σ is the population standard deviation and n is the sample size.

Plugging in the given values, we get:

SE = 27/√36 = 27/6 = 4.50

Therefore, the answer is B.
