Chronic liver disease is associated with poorer health outcomes, including renal disease and cardiovascular diseases. Given this, a group of public health consultants are interested in identifying risk factors for chronic liver disease among 72 men. They found that compared to men without hepatitis B, the relative risk of chronic liver disease among those with hepatitis B was 1.24 and the 95% confidence interval was 0.94–1.54.   A) Interpret the results (the relative risk and the corresponding 95% confidence interval) in not more than 75 words   B) The confidence interval for the best estimate appears to be wide. What could be the reason? Justify in not more than 75 words.
