16%
26%
73%
98%

Answer 1

26% is the answer to your question

Answer 2

The correct option is 2.

Explanation:

We have to find the value of P(0.6 ≤ z ≤ 2.12).

`P(0.6\leq z\leq 2.12)=P(z\leq 2.12)-P(z< 0.6)`

From the Cumulative Standardized Normal Distribution table,

`P(z\leq 2.12)=0.9830`

`P(z<0.6)=0.7257`

`P(0.6\leq z\leq 2.12)=0.9830-0.7257`

`P(0.6\leq z\leq 2.12)=0.2573`

`P(0.6\leq z\leq 2.12)\approx 0.26=26\%`

Therefore the correct option is 2.
