Question

The number 0.6064 represents the area under the standard normal curve below a particular z-score. What is the Z-score? Express the answer as a decimal to the hundredths place.


Note: I am having a hard time with this assignment and I would gladly appreciate someone describing exactly what they did to get the answer. Thanks :)

Answer 1

p(z < x) = 0.6064 - 0.5 = 0.1064

From the normal distribution table
P(z < 0.27) = 0.1064

Therefore the z-score is 0.27

I can't explain it very well for you, sorry. 

Answer 2

z = invNorm(.6064) = .2699 0r .27 (to the nearest hundredth) z = .27 Area to the left of the Green Line(where z = .27) is 60.64% of the Area under the standard Normal Curve.
