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, 
So, using the normal distribution, we first find the value of z.

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.
