2.n = 210, p= 0.45, 90% confidence interval

3.n = 90, p= 0.55, 99% confidence interval

II - Given the following sample data and confidence level, construct the confidence interval estimate of the population proportion p.

1.n = 160, x = 64, 95% confidence interval

2.n = 210, p= 0.45, 90% confidence interval

3.n = 450, p= 0.55, 99% confidence interval

1.0.325 < p < 0.575

2.0.137 < p < 0.563

3.0.088 < p < 0.912

Find the length of the confidence interval given the following data:

1.p= 0.35, n = 400, 95% confidence level

2.p= 0.40, n = 290, 90% confidence interval

3.p= 0.49, n = 360, 99% confidence intrval

4.= 0.5. n = 36, 95% confidence level

5.= 0.38, n = 38, 99% confidence interval

6.s = 5.25, n = 14, 95 confidence interval

7.s2= 30.25, n = 28, 90% confidence interval

III - Find the sample size required to estimate a population proportion given the following data:

1.confidence level = 95%

p = 29%

margin of error = 3.6%

2.confidence level = 90%

p = 45%

margin of error = 4.6%

3.confidence level = 99%

p = 0.55

margin of error = 0.048

4.Margin of error = 0.056

Confidence level = 90%

p is unknown

5.Margin of error = 0.062

Confidence level = 99%

p is unknown
