Consider a 95 percent confidence interval constructed for the difference between two population
proportions PR and Ps. The interval for PR - Ps is given as (-0.05, 0.15). Which of the following is an
appropriate interpretation of the confidence level?
In repeated random sampling with the same sample size, êr - Ộs will be contained in
the interval approximately 95 percent of the time.
In repeated random sampling with the same sample size, PR will be contained in the
interval approximately 95 percent of the time.
In repeated random sampling with the same sample size, Ôr will be contained in the
interval approximately 95 percent of the time.
The probability is 0.95 that the difference in the sample proportions PR - Ổs is between
-0.05 and 0.15
In repeated random sampling with the same sample size, approximately 95 percent of the
intervals will capture the difference in population proportions, PR - Ps.
