find the area of the shaded region. the graph depicts the standard normal distribution of bone density scores with mean 0 and standard deviation 1.\nthe area of the shaded region is \n(round to four decimal places as needed.)

Answer

Explanation:

Step1: Use z - table lookup

We need to find the area to the right of z = - 1.12 in the standard normal distribution. The standard normal table gives the area to the left of a z - score. The total area under the standard normal curve is 1.

Step2: Find area to the left

Looking up z=-1.12 in the standard normal table, the area to the left of z = - 1.12 is 0.1314.

Step3: Calculate area to the right

The area to the right of z=-1.12 is (A = 1 - 0.1314=0.8686).

Answer:

0.8686
