Answer:
B. 3.2
Explanation:
The standard error of the sampling distribution is obtained using the formula below:
[tex]\begin{gathered} SE=\frac{\sigma}{\sqrt[]{n}} \\ \sigma=32 \\ n=100 \end{gathered}[/tex]Therefore:
[tex]\begin{gathered} SE=\frac{32}{\sqrt{100}} \\ =\frac{32}{10} \\ =3.2 \end{gathered}[/tex]The correct choice is B.
