At an archaeological site 130 skeletons are found and their heights are measured and found to be approximately normal with mean 172 centimeters and variance 81. At a nearby site, five skeletons are discovered and it is found that the heights of exactly three of them are above 185 cm. Based on this information is it reasonable to assume that the second group of skeletons belongs to the same family as the first group of skeletons? Provide probabilities to support your answer
