How do it Find the z-scores corresponding to the given areas under the standard normal distribution "bell curve".
What does it mean by left and right
The area to the left of z is 15%
The area to the right of z is 65%.
The area to the left of z is 10%.
The area to the right of z is 5%.
The area between -z and z is 95%. (Hint draw a picture and figure out the area to the left of the -z)
The area between -z and z is 99%.
Mean μ = 0 and standard deviation σ = 1
