The correct answer is:

**A. More than 95% of healthy adults have a body temperature greater than 96.8°F.**

This statement cannot be supported because, with a normal distribution centered around 98.2°F, only a smaller percentage would fall significantly below this mean.

The distribution of body temperature for healthy adults is approximately normal with mean 98.2°F and standard deviation 0.7°F. Based on the description of the distribution, which of the following statements CANNOT be supported?

A) More than 95% of healthy adults have a body temperature greater than 96.8°F.
B) The first quartile of the distribution of healthy adults' body temperature is less than 97.5°F.
C) Approximately 50% of healthy adults have a body temperature greater than 98.2°F.
D) Approximately 95% of healthy adults have a body temperature between 96.8°F and 99.6°F.
E) A body temperature of 100.3°F or more would occur in less than 2% of healthy adults.
