6 Find two z values, one positive and one negative, so that the areas in the two tails total the
following values.
a. 5%
· Look at the corresponding value of (0.5000 - 0.0250 = 0.4750).
· z = +1.96 and z = -1.96 are the two values of z.
b. 10%
· Look at the corresponding value of (0.5000 – 0.0500 = 0.4500).
· z = +1.645 and z = -1.645 are the two values of z.
c. 1%
· Look at the corresponding value of (0.5000 – 0.0050 = 0.4950).
· z = +2.575 and z = -2.575 are the two values of z.

5 Find two z values so that 44% of the middle area is bounded by them.
· Look at the corresponding value of 0.22.
· z = +0.58 and z = -0.58 are the two values of z.
هي محلوله بس مو عارفه كيف انحلت بلييييييييييز الله يخليكم احد يشرحلي
