Answer: It is such a small percentage of the population that would be considered to have fever at that level.
So, it is not appropriate stringent standard.
Step-by-step explanation:
Since we have given that
Mean = 98.20°F
Standard deviation = 0.62°F
If  Bellevue Hospital in New York City uses 100.6°F as the lowest temperature considered to be a fever.
So, [tex]\bar{X}=100.6^\circ F[/tex]
So, using the normal distribution, we first find the value of z.
[tex]z=\dfrac{\bar{x}-\mu}{\sigma}\\\\x=\dfrac{100.6-98.2}{0.62}\\\\z=3.87[/tex]
Since z = 3.87
So, p = 0.0001 =0.1%
So,It is such a small percentage of the population that would be considered to have fever at that level.
So, it is not appropriate stringent standard.
