For patients with a history of osteomyelitis, it is desired to study a tannium implant method. Suppose the The effectiveness of the tannium implant is determined by the amount of bone growth 1 year after place the implant. The mean bone growth for patients with no history of previous infection is about 3.2 mm. Based on her clinical experience, Dr. Calderón believes that bone growth in patients with a history of previous infection is slower than that of those without a medical history. To confirm her belief, Dr. Calderón wishes to test her hypotheses with a level of significance! = 0.05. In fact, You want to be able to detect a significant difference of 0.9 mm with a probability of 0.90. Suppose the The amount of bone growth is normally distributed with a variance &2 = 2.68.
