Based on the sample results in Data Set 18 of Appendix B, assume that human body temperatures are normally distributed with a mean of 36.4°C and a standard deviation of 0.62°C. If we define a fever to be a body temperature above 37.8°C, what percentage of normal and healthy persons would be considered to have a fever? Does this percentage suggest that a cutoff of 37.8°C is appropriate? |
