Draw the Different normal curves.

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. z=-0.85 and z=1.29

Calculate the z-score representing the bottom 10% of an approximately normal distribution. (Use a table or technology. Round your answer to two decimal places.)

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.  The are of the shaded region is _____ (Round to four decimal places as needed.)

A bottler of drinking water fills plastic bottles with a mean volume of 994 millimeters (mL) with a standard deviation of 5 mL.  The fill volumes are normally distributed.  What proportion of bottles have volumes less than 995 mL?  Use Table A.2 (Normal Distribution Table) and keep four decimal places with your answer.

Find the area of the shaded region. The graph to the right depicts IQ scores of​ adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15.                     97         A symmetric bell-shaped curve is plotted over a horizontal scale. A vertical line runs from the scale to the curve at labeled coordinate 97, which is to the left of the curve’s center and peak. The area under the curve to the right of the vertical line is shaded.       Question content area bottom Part 1 The area of the shaded region is enter your response here. ​(Round to four decimal places as​ needed.)
