Sleep deprivation, CA vs. OR.
According to a report on sleep deprivation by the Centers for Disease Control and Prevention, the proportion of California residents who reported insufficient rest or sleep during each of the preceding 30 days is 8
%, while this proportion is 9.2% for Oregon residents. These
data are based on simple random samples of 11744 California and
4725 Oregon residents. Calculate a 96% confidence interval for the

who are sleep deprived and interpret it in context of the
data.
