Given:

\(\displaystyle\mu={5.2}\)

\(\displaystyle\sigma={0.3}\)

x=5.4

\(\displaystyle{z}=\frac{{{x}-\mu}}{\sigma}\)

\(\displaystyle=\frac{{{5.4}-{5.2}}}{{0.3}}\)

\(\displaystyle\approx{0.67}\)

Use the normal probability table in the appendix to determine the corresponding probability. P(z

P(x

=74.86%

Approximately 74.86% of people have less than 5.4 liters of blood.
