If you are constructing a confidence interval for a population mean, for the same confidence level, the width of the confidence interval will __________ as the sample size increases.

  • Decrease
  • Increase
  • Stay the same
  • Depends on the sample size

Suppose a 95% CI for the population proportion is [0.35, 0.45]. How should we interpret this confidence interval?

  • There is a 95% chance that the population proportion lies between 0.35 and 0.45
  • We are 95% confident that the population proportion lies between 0.35 and 0.45
  • Both of the above are correct
  • None of the above
