According to the National Health Survey, the heights of adult males in the United States are normally distributed with mean 69.0

liberstina [14]

Answer: (a) 0.927

(b) 14.2%

Explanation:

Given : According to the National Health Survey, the heights of adult males in the United States are normally distributed .

Mean : $\mu=69$

Standard deviation : $\sigma=2.8$

Let X be a random variable that represents the heights of adult males in the United States .

Z-score : $z=\dfrac{x-\mu}{\sigma}$

(a) For x= 64

$z=\dfrac{64-69}{2.8}\approx-1.79$

For x= 74

$z=\dfrac{74-69}{2.8}\approx1.79$

Using the standard normal distribution table , we have

The deviation 2.8 inches. (a) What is the probability that an adult male chosen at random is between 64 and 74 inches tall :-

$P(64$

Hence, the probability that an adult male chosen at random is between 64 and 74 inches tall = 0.927

b) Since 1 feet = 12 inches

Then , 6 feet = $6\times12=72\text{ inches}$

The z-score corresponds to x=72 :

$z=\dfrac{72-69}{2.8}\approx1.07$

Then , the probability that the adult male population is more than 6 feet tall :-

$P(x>72)=P(z>1.07)=1-P(z$

Hence, the percentage of the adult male population is more than 6 feet tall = 14.2%

What do the arrows in food chains/webs represent?

nasty-shy [4]

Most generally speaking, the arrows in the food webs/chains represent the flow of energy.

Most typically, the energy will flow from the Sun to the plants, and then those plants are eaten and when they are eaten the energy flows from the plants to whatever animal ate them.
