Assume that human body temperatures are normally distributed with a mean of 98.22 degrees Upper F 98.22°F and a standard deviati

Anna35 [415]

Answer: 0.00102%

Step-by-step explanation:

Given : Human body temperatures are normally distributed with a mean of $\mu=98^{\circ}F$ and a standard deviation of $s=0.61^{\circ}F$

A hospital uses $100.6^{\circ}F$ as the lowest temperature considered to be a fever.

Let x be the random variable that represents the human body temperatures.

$z=\dfrac{x-\mu}{s}$

For x= 100.6, $z=\dfrac{100.6-98}{0.61}=4.26229508197\approx4.26$

Using normal distribution table for z-values for right-tailed area ,

P(x>100.6)= $P(Z>4.26)=0.0000102=0.00102\%$

Hence, the required probability = 0.00102%

if you are told only that you scored 80th percentile do you know from the description exactly how it wad calculated? Explain

Dmitriy789 [7]

We know that there is no universal acceptance meaning of a percentile. When someone told you that you are in the 80th percentile, the meaning of that is you have achieved the lowest score that is greater than 80 percent of the score. It is calculated by using the formula R = P/100 x (N + 1)
