Respuesta :
Using the Empirical Rule, it is found that 95% of the employees will have a travel time within the following range:
B. 8 minutes to 28 minutes.
What does the Empirical Rule state?
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Considering that the mean time is 18 minutes and the standard deviation is 5 minutes, the the bounds of the 95% range are given by:
- 18 - 2 x 5 = 8 minutes.
- 18 + 2 x 5 = 28 minutes.
Hence option B is correct.
