Answer

Answer:

$8%$

Explanation:

Step1: Recall normal - distribution property

The total area under the standard normal curve is 1, i.e., $P(Z\lt+\infty)=1$. Also, $P(Z\geq z)=1 - P(Z\lt z)$. For $z = 1.4$, $P(Z\geq1.4)=1 - P(Z\lt1.4)$.

Step2: Use the standard - normal table

Looking up $P(Z\lt1.4)$ in the standard - normal table, we find that $P(Z\lt1.4)=0.9192$.

Step3: Calculate $P(Z\geq1.4)$

$P(Z\geq1.4)=1 - 0.9192=0.0808$.

Step4: Convert to percentage and round

$0.0808\times100 = 8.08%$. Rounding to the nearest percent gives $8%$.
