haven't touched this in a few weeks because of extended spring break, but these are our notes for the next chapter. why is the standard deviation s different from the standard deviation given? I can't find any notes that say how to find s from the given standard deviation
I tried [math]\sqrt{30}*\frac{3}{4.09} = 4.0175[/math](found 4.09 by multiplying 2 by t table value of 2.045)
is this just a rounding difference?
