Assume that a randomly selected subject is given a bone density test. bone density test scores are normally distributed with a mean of 0 and a standard deviation of 1. draw a graph and find upper p 3p3, the 3 rd3rd percentile. this is the bone density score separating the bottom 3 %3% from the top 97 %.
450 is the final answer! : )
the pertinent area formula is a = πr², where r is the radius.
here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
