At least 89% of the data

Minimum = 96.34 F

Maximum=  100.06 F

Step-by-step explanation:

According to the  Chebyshev's theorem 89% of the data are within the 3 standard deviations of the mean.

The mean body temperature is 98.20 F  and standard deviation is 0.62 F

Mean- 3SD= 98.20 F- 3(0.62)=  98.20 F- 1.86= 96.34 F

Mean + 3SD= 98.20 F + 3(0.62)=  98.20 F+ 1.86= 100.06 F
