In a recent statistics survey, 37 out of 129 randomly sampled college students said they get enough sleep. Penn State conducted a much larger scale study a few years ago and found that 40% of college students got enough sleep. Is the lower percentage among college students in the recent study due to chance or is it signifcantly lower than the Penn State study? Determine the alpha level for this study.

In a city of 80,000 households, 800 were randomly sampled in a marketing survey by an auto manufacturer. To see how typical this city was, some statistics were collected: the average number of cars per household was 1.32, while the standard deviation for the number of cars per household was 0.8. Construct a 95% confidence interval for the average number of cars per household in the whole city.
