Forced expiratory volume (FEV) is a measure of lung capacity, in liters. Initial measurements provide a baseline value to study the impact of smoking on lung function in the population. Data are obtained on the FEV of a random sample of 100 youths in East Boston in the late 1970s. The sample mean FEV value is 2.3948 liters and the sample standard deviation is 0.80287 liters. The 90% confidence interval for the population mean is (2.26156 liters, 2.52818 liters). Select the correct interpretation of this confidence interval. Group of answer choices
