Question 938354: 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
If bone density scores in the bottom 2.5% and the top 2.5% are used as cutoff points for levels that are too low or too high, find the two readings
that are cutoff values.

For the normal distribution: Below: z = 0, z = � 1, z= �2 , z= �3 are plotted.
Area under the standard normal curve to the left of the particular z is P(z)
Note: z = 0 (x value: the mean) 50% of the area under the curve is to the left and 50% to the right

.....
mean of 0 and a standard deviation of 1.
z = invNorm(.025) = X/1
invNorm(.025) = X = -1.96
invNorm(.975) = X = 1.96
...
(-1.96, 1.96)
