Question

1) Bone Density Test A bone mineral density test is used to identify a bone disease. The result of a bone density test is commonly measured as a Z score, and the population of Z scores is normally distributed with a mean of O and a standard deviation of 1.

Answer 1

volcttion: Borse Denssity fost A bone mineral density test its cibed :- 1 Roxired information is given by M0, mean -:1. Gansbord deviation and 7scores are -1.60 and 8.30 Calcalate :- Find the probability of abose density fall Score betwen 7.80 and 9.00 We have to obtained the probability of abone density test - (score between -1.00 and peois, Here, probability is PE=1.Bo<t<.eol >>P17 (2.20)- P[7<7:30] >> P17<9.30) – (1-AZ<1.30]] - (0.9898 - (-0.9032)] >>. 9893 - 0.09687 -> 0.8905) there for Deorried probability is 0.8905)
