Question 3

3. In a study by Wang et al., researchers examined bone strength. They collected 4 cadaveric femurs from subjects in three age groups: young (19 49 years), middle-aged (50 69 years), and elderly (70 years or older). One of the outcome measures (W) was the force in Newtons required to fracture the bone. The following table shows the data for the three age groups. Young (Y) Middle-age (MA) Elderly (E) 9.0 8.0 4.0 7.0 5.0 3.0 10.0 8.0 6.0 4.0 3.0 2.0 Do these data provide sufficient evidence to indicate a difference in three age groups: young (19 49 years), middle-aged (50-69 years), and elderly (70 years or older)? Let a = 0.05
