Yuri [45]

Answer:

The probability is "0.6406", this elevator isn't appear to be safe

Step-by-step explanation:

The given values are:

Mean,

$\mu=165$

Standard deviation,

$\sigma=35$

Number of male passengers,

$n = 10$

Now,

⇒ $z=\frac{161-165}{\frac{\sigma}{\sqrt{10} } }$

$=\frac{161-165}{\frac{35}{\sqrt{10} } }$

hence,

The probability will be:

= $P(\bar {x}>161)$

= $P(z > -0.3614)$

= $0.6406$
