Answer: A. 1.2
Step-by-step explanation:
Given : Sample size : n= 64
Standard deviation: 
The formula to find the standard error of mean is given by :-

Therefore, the standard error of the mean= 1.2
Hence, A is the right option.
Your Answer Is...
A) 0.
Why?
This is correct because if 3 = b + 3, then ? + 3 = 3. 0 + 3 = 3, making the answer A) 0.
