I was having a bit of trouble with question 18. Thank you!

QUESTION 18 The distribution of total body protein in adult men with liver cirrhosis is approximately Normal with standard deviation o = 0.1 kg. A 95% confidence interval for the true mean total body protein of adult men with liver cirrhosis, based on 67 randomly selected adult males with liver cirrhosis, has a margin of error of 0.024 kg. If the study had enrolled more subjects, the resulting width of a 95% confidence interval would be the same. would be larger. would be smaller. may be different, but that would depend on the actual sample mean. QUESTION 19 The distribution of total body protein in adult men with liver cirrhosis is approximately Normal with standard deviation o = 0.1 kg. A 95% confidence interval for the true mean total body protein of adult men with liver cirrhosis, based on 67 randomly selected adult males with liver cirrhosis, has a margin of error of 0.024 kg. If the study had changed their alpha to 0.01, the resulting width of the confidence interval would stay the same would be larger would be smaller would depend on whether the sample mean changed
