Question: Following is the data I collected from your class and the class I taught this summer on the number of hours of sleep you reported receiving the night before the first class.

Fall, 2008

Summer, 2008

Calculate 95% confidence intervals for the amount of sleep students receive using the data for each class. Compare the intervals for each class and comment on whether they appear to come from the same or different populations. Does either class appear to get the required 8 hours of sleep? Explain your reasoning.
