In a medical study involving one hundred pairs of identical twins, one member of each pair tests positive for a particular disease, while the other member of each pair does not. One researcher noted that the average body temperature of those who have the disease is 98.0°, and the average body temperature of those who do not have the disease is 98.3°. The researcher then concludes, "People who have this particular disease have a lower body temperature." Why is this probably not a valid claim?

Well, i would think it's not a valid claim because 98.0 is normal for anyone a baby, toddler, infant, and adults so as 98.3. so i think the it's invalid because 98.0 and 98.3 F is normal for either identical set whether they have the disease or not.
