1) Consider random samples of size 55 from a population with proportion 0.35. Find the standard error of the distribution of sample proportions.

(Round your answer for the standard error to three decimal places.)

Standard error = _____

2)Consider random samples of size 1100 from a population with proportion 0.65. Find the standard error of the distribution of sample proportions.

(Round your answer for the standard error to three decimal places.)

Standard error = _____

3) Use the normal distribution to find a confidence interval for a proportion p given the relevant sample results. Give the best point estimate for p, the margin of error, and the confidence interval. Assume the results come from a random sample.

A 95% confidence interval for p given that ^p=0.38 and n=550.

(Round your answer for the best point estimate to two decimal places, and your answers for the margin of error and the confidence interval to three decimal places.)

Best point estimate = _____

Margin of error = ± _____

The 95% confidence interval is _____
