For each of the following z-score locations in a normal distribution, determine whether the tall is on the left side or the right side of the distribution and find the proportion that is located in the tail.

A. z = +1.75

B. z = +0.80

C. z = -0.70

D. z = -1.65

Solution

A. z = +1.75.

Tail on the right. Area = 0.0401

B. z = +0.80

Tail on the right. Area = 0.2119

C. z = -0.70

Tail on the left. Area = 0.242

D. z = -1.65

Tail on the left. Area = 0.0495
