Final answer:
The area between z = 1.1 and z = 2.1 is 0.8185.
Step-by-step explanation:
The area between z = 1.1 and z = 2.1 can be found by subtracting the area to the left of z = 1.1 from the area to the left of z = 2.1. The table given states that the area to the left of a z-score of 1.1 is 0.1587, and the area to the left of a z-score of 2.1 is 0.9772. To find the area between the two z-scores, we subtract the smaller area from the larger area: 0.9772 - 0.1587 = 0.8185. Therefore, the area between z = 1.1 and z = 2.1 is 0.8185.
