Finding Bone Density Scores. In Exercises 37-40 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. In each case, draw a graph, then find the bone density test score corresponding to the given information. Round results to two decimal places.

- Find P99, the 99th percentile. This is the bone density score separating the bottom 99%

from the top 1%. - Find Pis, the 15th percentile. This is the bone density score separating the bottom 15%

from the top 85%. - If bone density scores in the bottom 1% and the top 1% are used as cutoff points forĀ levels that are too low or too high, find the two readings that are cutoff values.
- Find the bone density scores that are the quartiles Q1, 2, and Q3.
