Normal human body temperature varies slightly from person to person and by time of day. The average normal human body temperatures, taken orally, is 98.6°F with the standard deviation of 0.9°F. Scientists consider any temperature in one standard deviation to be normal.
1. Determine the temperature associated with a standard deviation of 1?
2. Determine the temperature associated with a standard deviation of -1?
3. Determine the range of temperatures that would be considered normal?
5. Determine the probability that a person has a temperature between -1 and 1 standard deviations?
6. Compute the z-score of a patients temperature at 101°F?
7. Estimate the probability that a persons temperature falls between 98.6°F and 101°F?
9. Compute the probability that a person temperature is above 101°F?
