Question

use the z table to find The probability associated with each of the following areas under a normal curve:

1. between a z-score of 0 and 1.2

2. between a z-score of -2.12 and 1.06

Answer 1

Part-1:

We need to find

From normal distribution table;

Hence, area under a normal curve between a z-score of 0 and 1.2 =

Part-2:

We need to find

From normal distribution table;

Hence, area under a normal curve between a z-score of -2.12 and 1.06 =
