Question: The total sleep time per night among college students is approximately Normally distributed with mean hours and standard deviation hours. You plan to take an SRS of size and compute the average total sleep time.
- What is the standard deviation of the average time?
- Use the 95 part of the Empirical Rule (68-95-99.7 rule) to describe the variability of this sample mean.
- What is the probability that your average will be below 6.8 hours?
