The commonly used value of human body temperature (in degrees Fahrenheit) is equal to 98.6.

To calculate the likelihood of the mean temperature value to be different from the commonly used value, the following expression is used:

\(\frac{{98.2 - 98.6}}{{\frac{{0.62}}{{\sqrt {106} }}}}\)

The probability that the average value of body temperature is different from the value of 98.6 degrees Fahrenheit is as calculated below:

\(\begin{aligned}{c}\frac{{98.2 - 98.6}}{{\frac{{0.62}}{{\sqrt {106} }}}} = \frac{{\left( { - 0.4} \right)}}{{0.06021}}\\ = - 6.642342\\ \approx - 6.64\end{aligned}\)

Thus, the probability that the average value of body temperature is different from the value of 98.6 degrees Fahrenheit is equal to \( - 6.64\).
