According to a report on sleep deprivation, the proportion of California residents who reported insufficient rest or sleep during each of the preceding30 daysis9.0%, while this proportion is9.9% for Oregon residents. These data are based on simple random samples of11,567California and4,684Oregon residents. Calculate a 95% confidence interval for the difference between the proportions of Californians and Oregonians who are sleep deprived and interpret it in context of the data. (Use p_CAp_OR. Round your answers to two decimal places.)

Before calculating the interval, we should check that the conditions are satisfied. The sample ---Select--- is/ is not random and the sample represents ---Select--- greater than/ less than 10% of all California and Oregon residents. Therefore whether or not one person in the sample reported insufficient rest or sleep ---Select--- is/ is not independent of another. The success-failure condition ---Select--- is /is not met since the number of successes and failures is ---Select--- less than /greater than 10. So, we are 95% confident that the difference between the proportions of Californians and Oregonians who are sleep deprived is between ? %and ? %.
