So, I think I know why they are confused; they want a number to be associated for the total; its given; the answer choices are the total (I assume). If the bat population had been 100, then 16% or 16 of them would have that trait.

anonymous · Answer

Thank you jonny, that would make sence

anonymous · Answer

yes, @JonnyVonny , while also keeping in mind that the standard deviation is less that 2

jonnyvonny · Answer

Yup, so, idk what that could mean. Hehe.

anonymous · Answer

hmmm....okay...Thanks for your help though!

In one company, the mean amount of time employees spend on the Internet each day is 3.2 h. The standard deviation is 0.8 h. A random sample of 32 employees is taken.

What is the approximate standard deviation in a sampling distribution of this size?

Round to the nearest thousandth.

would anyone know the solution to this one?
