valkas [14]

Answer:  A. 1.2

Step-by-step explanation:

Given : Sample size : n= 64

The formula to find the standard error of mean is given by :-

S.E.=\dfrac{\sigma}{\sqrt{n}}\\\\\Rightarrow\ S.E.=\dfrac{9.6}{\sqrt{64}}\\\\\Rightarrow\ S.E.=\dfrac{9.6}{8}=1.2

Therefore, the standard error of the​ mean= 1.2

Hence, A is the right option.
