The text describes a statistical problem related to body temperature, assuming normal distribution with specific parameters. Here is the transcription: --- Suppose body temperatures are normally distributed with a mean of 98.2°F and a standard deviation of 0.62°F. a) If a body temperature of 100.2°F or above is considered to be a fever, what percentage of healthy people would be considered to have a fever? a) [ ] b) What body temperature corresponds to the upper 40% cutoff point? b) [ ] --- **Explanation:** The question involves two tasks related to the normal distribution of body temperatures: - **Part (a)** requires calculating the percentage of the population with a body temperature of 100.2°F or above, by determining the area in the upper tail of the distribution beyond this cutoff. - **Part (b)** requires identifying the body temperature corresponding to the 60th percentile (since the upper 40% cutoff implies finding the temperature below which 60% of temperatures fall). No graphs or diagrams accompany the text. In a study of a large group of individuals who used cell phones regularly, it was found that some developed brain cancer with a probability of 0.00034. In a randomly selected group of 420,095 cell phone users, find the probability that the number of people who developed brain cancer is: a) At least 138 people [Blank Box for answer] b) Between 130 and 145 people [Blank Box for answer]

![The text describes a statistical problem related to body temperature, assuming normal distribution with specific parameters. Here is the transcription:
---
Suppose body temperatures are normally distributed with a mean of 98.2°F and a standard deviation of 0.62°F.
a) If a body temperature of 100.2°F or above is considered to be a fever, what percentage of healthy people would be considered to have a fever?
a) [ ]
b) What body temperature corresponds to the upper 40% cutoff point?
b) [ ]
---
**Explanation:**
The question involves two tasks related to the normal distribution of body temperatures:
- **Part (a)** requires calculating the percentage of the population with a body temperature of 100.2°F or above, by determining the area in the upper tail of the distribution beyond this cutoff.
- **Part (b)** requires identifying the body temperature corresponding to the 60th percentile (since the upper 40% cutoff implies finding the temperature below which 60% of temperatures fall).
