Confidence Interval Simulation

Confidence Interval Demonstration

Questions

Question 1 out of 4.

What proportion of 95% confidence intervals for the mean do not contain the population mean?

Question 2 out of 4.

Which is wider, a 95% confidence interval or a 99% confidence interval?

  1. 95% interval
  2. 99% interval
Question 3 out of 4.

How does sample size affect the probability that the interval will contain the population mean?

  1. The larger the sample size, the higher the probability the interval will contain the population mean.
  2. The larger the sample size, the lower the probability the interval will contain the population mean.
  3. Sample size has no effect on the probability the interval will contain the population mean.
Question 4 out of 4.

Is it possible for the 95% interval to contain the population mean while the 99% confidence interval does not?

  1. Yes
  2. No
