A single sample T-test is to be done on a study about typhoons. Many believe that the average number of typhoons that enter the Philippines each year is 18 (μ ≥ 18).

An important indicator of lung function is forced expiratory volume (FEV), which is the volume of air that a person can expire in one second. Dr. Hernandez plans to measure FEV in a random sample of n individuals from a certain population, and to use the sample mean to estimate of the population mean. The population distribution of FEV is assumed to be normal with mean mu-3000 ml and SD sigma=400 ml. Which of the following statements is correct regarding the sampling distribution of the sample mean? Ⓒa. It is the theoretical distribution of a sample statistic (in this case the sample mean). b.
