Peak expiratory flow (PEF) is a measure of a patient’s ability to expel air from the lungs. Patients with asthma or other respiratory conditions often have restricted PEF. The mean PEF for children free of asthma is 306. An investigator wants to test whether children with chronic bronchitis have restricted PEF. A sample of 50 children with chronic bronchitis is studied, and their mean PEF is 274 with a standard deviation of 59. When you run the appropriate test at a = 0.05, the appropriate conclusion to whether there statistical evidence of a lower mean PEF in children with chronic bronchitis is?
