To determine

To check: Whether the statement is true or false.

Explanation

Reason for correct answer:

For a population with a mean of μ=40 and standard deviation of σ=8, the standard error for a  mean can never be larger than 8.

The formula for standard error is,

σM=σn

For n=1:

The value of standard error is,

σM=σn=8
