The following data represents the body temperature in degrees Fahrenheit of randomly selected adults: 98.3 98.8 98 98.8 98.3 99 98.1 98.4 99.4 98.8 99.3
Mean is 98.7
Standard Deviation is 0.5
Use the Empirical Rule to answer the following
question: What is the probability, in decimal form, of a body temperature less than 97.2?

Answer:

To use the Empirical Rule, you can consider approximately 68% of the data falling within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations.

Given the mean of 98.7 and a standard deviation of 0.5, the range for one standard deviation below the mean is \(98.7 - 0.5 = 98.2\).

Since 97.2 is below this range, it falls within the first standard deviation. Therefore, the probability of a body temperature less than 97.2 is approximately 0.68.
