Clinical research attempts to identify the risks of exposure to the population in the workplace. In a group of 46 men Between the ages of 25 and 36, changes in the function of their lungs have been measured. One of the variables of interest was the volume exhalation force (VFE), which is the volume of air exhaled per second. At the end of a certain period, it was found that the VFE of ` this sample decreased with an average of 0.27 liters and a deviation 0.52 liter sample type. We know that the VFE increases by 0.1 liter in healthy men of the same age during the same period of time. Can we conclude that the middle of work of this group plays a significant role in the growth of VFE greater than 0.1 liter? Choose the appropriate hypothesis test to do. Give the value - P and your conclusion. Take α = 0.02.
