The best way to check the buoyancy of your PFD is to
try wearing it in a pool or shallow water and see how it works. To test the
PFD, it must be worn correctly where straps, zippers and ties are properly fastened and any loose
ends should be tucked away. Then try to relax your body and let your
head tilt back. Your PFD must allow you for a comfortable swim without any
restrictions. Nevertheless, the best test of all is to jump into a pool by feet
first. Your PFD must stay in place and not ride up, pop off over your head or
slip over your chin.
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%
