what is the bone density? please.

This Question: nit Quiz This-Quiz: 10 pts possible ar 1 pt 7 of 10 Assume that a randomly selected subject is given a bone density test. Those test scores are normally di a graph and find the bone density test scores that can be used as cutoff values separating the lowest 69% and high respectively stributed with a mean of 0 and a standard deviation of 1. Draw est 6%, indicating levels that are too low or too high. Sketch the region. Choose the correct graph below. O A. OB. O C. D. Ze The bone density scores are (Use a comma to separate answers as needed. Round to two decimal places as needed.) Click to select your answer(s). Save for Later 8:10

Explanation / Answer

Here answer is option d)
In this curve two lines at -Za and at Zal seperates the lower 6% and upper 6% See the option d)

Ans: d)

Now we have to find Za Such that

P( Z< Za) = 0.06

From Z table we get P( Z< -1.56) = 0.0594

Which is approximately 0.06

So -Za= -1.56

We know that Z is symmetric so Za= 1.56

So above density scores are -1.56, 1.56
