Question

Given below is information from a study on lung capacity.

Interpret the 95% Confidence Interval.



Total theoretical male population mean: 6.00
Your sample mean: 6.05
95% Confidence interval: (5.5, 6.5)


Question 5 options:

A. We can be 95% confident that the sample mean comes from a different population than the population mean

B. 95 of 100 confidence intervals from separate samples taken from this population will contain the true mean

C. The confidence interval shows us that the sample mean has a 95% chance of being higher than the theoretical mean

D. The sample mean is 95% more likely to be in the confidence interval than the population mean
