Question

Millions of North Americans spend up to several hours a day commuting to and from work.
Other than the wasted time are there other negative effects associated with fighting traffic? A study by Statistics Canada may shed light on the issue.
A random sample of adults was surveyed. Among other questions each was asked how much time he or she slept and how much time was spent commuting. The categories for commuting time are 1 to 30 minutes, 31 to 60 minutes, and over 60 minutes. Is there sufficient evidence to conclude that the amount of sleep differs between commuting categories?
