Suppose a population has a mean of 7 for some characteristic of interest and a standard deviation of 9.6. A sample is drawn from

valkas [14]

Answer: A. 1.2

Step-by-step explanation:

Given : Sample size : n= 64

Standard deviation: $\sigma=9.6$

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.
