The distribution of total body protein in healthy adult men is approximately Normal, with standard deviation = 0.1 kg. A 95% confidence interval for the true mean total body protein of adult men with liver cirrhosis, based on 58 randomly selected adult males with liver cirrhosis, has a margin of error of 0.026 kg. How would a 90% confidence interval based on the same study compare to the 95% confidence interval? The 90% confidence interval would have a smaller margin of error. The 90% confidence interval may have a different margin of error, but that would depend on the actual sample mean. The 90% confidence interval would have a larger margin of error. The 90% confidence interval would have the same margin of error.
