A study was carried out to determine if boys at the age of twelve have lower bone mass than girls of the same age. The bone mineral content of the lumbar spine in 8 twelve-year-old boys was measured (Y). The results were then compared with that of 8 twelve-year-old girls ( X). The summaries of the data are: 7 = 0.85 g/cm, y = 0.79 g/cm, 8, = 0.08, 8, = 0.08. Please answer Questions 3-5 based on this information.
