For the sample data below, construct four different interval estimates of the population mean, one each for the 90%, 95%, 99%, and 99.9% level. What happens to the interval width as confidence level increases? Why?

X = 100

s = 10

n = 500

For each of the three sample sizes below, construct the 95% confidence interval. Use a sample proportion of 0.40 throughout. What happens to interval width as sample size increases? Why?

P_s
=- 0.40

Sample A: n = 100

Sample B: n = 1,000

Sample C: n = 10,000
