Explanation:
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 : 
Standard deviation : 
Let X be a random variable that represents the heights of adult males in the United States .
Z-score : 
(a) For x= 64

For x= 74

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 :-

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 = 
The z-score corresponds to x=72 :

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

Hence, the percentage of the adult male population is more than 6 feet tall = 14.2%
A web of causation model can vaccines and improved sanitation cause the death rate to decrease.
<h3>What web of causation model?</h3>
A web of causation model is a model designed to relate the causes and effects of a disease, exploring multiple causative factors and giving each same attention for such chronic disease.
For example, a web of causation model for a person who contracted Corona virus would study the factors involved relating to how such person may have contracted this disease, any health factors that make the person prone to contracting the virus etc.
Thus, Web of causation model is an epidemiological model used to organize research so as to identify determinant factors and provide relevant interventions and cure to a chronic disease.
