$1.4 \leq z < 1.6$

Step 1

Find the value in a look up table of the probability of a z-score of less than $0.41927077$ .

$z = 1.4$ has an area under the curve $0.41927077$

Step 2

Find the value in a look up table of the probability of a z-score of less than $0.4452262$ .

$z = 1.6$ has an area under the curve $0.4452262$

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.

$0.4452262 - (0.41927077)$

Step 4

Find the area between the two z-scores.
