Pretend you calculate a 95% confidence interval for the mean cholesterol level of University of Virginia students based on a sample of 25 students.The result is 150 a.P (150 b.P (m <150) and P (m >190) = .05 c.We are 95% confident that m lies between 150 and 190 d. If we took another (random) sample from this population, the resulting confidenceinterval should be numerically different than the above one. e.P (150< x-bar <190) = .95 f.The mean of the population in question is unlikely to be much smaller than 150 or much larger than 190. g.If we took another sample from this population but used a sample size of 49, we would expect the resulting interval to be wider. h.If we took another sample from this population but used a confidence level of 99%, we would expect the resulting interval to be wider
