Find the z-score corresponding to the given area.  Remember, z is distributed as the standard normal distribution with mean of μ = 0 and standard deviation σ = 1.

(a) The area to the left of z is 25%.

(b) The area to the right of z is 65%.

(c) The area to the left of z is 10%.

(d) The area to the right of z is 5%.

(e) Find the value for z such that the area between –z and z is 95%. (Hint: Drawing a picture might help.)

(f) Find the value for z such that the area between –z and z is 99%. (Hint: Drawing a picture might help.)
