The mean body temperature of a human is accepted to be98.6F. In a study, the body temperatures of127individuals were measured. The mean body temperature of the individuals was calculated to be99.0F. Assuming the regular body temperature of humans is actually98.6F, the probability of these results occurring by chance is less than0.01. Interpret the results of the calculation.

Select the correct answer below:

a. We can expect that the mean body temperature of any127 individuals is99.0F.

b. The mean body temperature of humans is not98.6F.

c. At the0.01 level of significance, the mean body temperature of humans is not98.6F.

d. Since human body temperature varies, the results of this study are not unusual.
