multiple choice question

If a researcher is constructing 95% confidence intervals, a. 95% of the time the computed interval will include the sample mean. b. 5% of the time such intervals will not include the population value. c. in the long run, 95% of all sample means will fall within the interval. d. 95% of the time the interval will not include the population value.

Solution

95% confidence interval for population mean means for the same sampling method to select different samples and computed an interval estimate for each sample, we would expect the true population parameter to fall within the interval estimates 95% of the time and 5% of time fall otuside the interval.

So option b is correct.
