$1.04 < z < 1.68$

Step 1

Find the value in a look up table of the probability of a z-score of less than $0.35086161$ .

$z = 1.04$ has an area under the curve $0.35086161$

Step 2

Find the value in a look up table of the probability of a z-score of less than $0.45354615$ .

$z = 1.68$ has an area under the curve $0.45354615$

Step 3

To find the area between the two z-scores, subtract the smaller z-score value from the larger one. For any negative z-score, change the sign of the result to negative.

$0.45354615 - (0.35086161)$

Step 4

Find the area between the two z-scores.
