Where should we start to help? Do you know the definitions of "median" and "standard deviation"?

Please show us what you have tried and exactly where you are stuck.

It mentions at least three formulas, and implies several more. What formulas were you taught?

Once you find the formulas, show us your attempt to use them, so we have some idea how much or how little you understand.

If this is homework, then memory is not the issue -- just look up the formulas in your textbook, because you're supposed to be learning them.

If it is a test and you're not allowed to look it up -- then you're not allowed to ask us, either.

So what's going on here?
