\sqrt{\frac{0.84\left(0.84\right)}{1010}} simplify as a percent

Describe the sampling distribution of p^ assume that the size of the population is 25,000 and n=1010, p=0.84

\sqrt{\frac{0.7\left(0.7\right)}{300}} simplified

Describe the sampling distribution of p^ assume that the size of the population is 25,000. n=300 p=0.7

Describe the sampling distribuation of p^ assume that the size of the population is 25,000. n=500 p=0.4

What happens to the standard deviation of p^ as the sample size increases? If the sample size is increased by a factor of 4 what happens to the standard deviation of p^?
