Suppose we take a sample of size 52 from a population with $\displaystyle \mu$  = 25 and $\displaystyle \sigma=$ 25.6

What is the standard deviation of the sampling distribution?

 $\displaystyle \sigma$  round to 1 decimal

Suppose you want to lower the standard deviation of the sampling distribution to 0.7, what sample size would be needed to accomplish this goal?

n =
