1. Build a 95% confidence interval estimate of the population proportion.

e = +/- 0.03.

You have no information about the value of "p." Hint: use: 0.5/0.5 rule.

What size of the sample would be needed?

2. Givens:

x = 200

= 0.1

n = 29

s =11

Build confidence interval estimate of the that reflect these condition by calculating:

a) point estimate

b) the upper confidence interval limit

c) the lower confidence interval limit
