Question

In a study of patients with heart failure, serum sodium levels are critical indicators of disease severity and prognosis. The mean of the normal blood sodium levels is 140 milliequivalents per liter (mEq/L). Low serum sodium often reflects fluid overload and worsened heart function. This problem explores the mean of serum sodium levels from a dataset that includes 299 patients who have experienced heart failure. Assume that the known true variance of serum sodium is 19.47.
