The purpose of a study by Ingle and Eastellwas to examine the bone mineral density (BMD) and ultrasound properties of women with ankle fractures. The investigators recruited 31postmenopausal women with ankle fractures and 31 healthy postmenopausal women to serve as controls. One of the baseline measurements was the stiffness index of the lunar Achilles. The meanstiffness index for the ankle fracture group was 76.9 with a standard deviation of 12.6. In thecontrol group, the mean was 90.9 with a standard deviation of 12.5. Do these data provide sufficient evidence to allow you to conclude that, in general, the mean stiffness index is higher inhealthy postmenopausal women than in postmenopausal women with ankle fractures?
