The minimum and maximum possible body temperatures that are within 3 standard deviations of the mean are 96.33 ° F and 100.29 ° F respectively.
By using the Chebychev's theorem, we know that at least 89% of the data values are within 3 standard deviations of the mean.
So, we get that:
Mean - 3 standard deviation = 98.31 ° F - 3 × (0.66 ° F)
= 98.31 ° F - 1.98 ° F
= 96.33 ° F
Mean + 3 standard deviation = 98.31 ° F + 3 × (0.66 ° F)
= 98.31 ° F + 1.98 ° F
= 100.29 ° F
Therefore, the minimum and maximum possible body temperatures that are within 3 standard deviations of the mean are 96.33 ° F and 100.29 ° F respectively.
