According to a report on sleep deprivation, the proportion of California residents who reported insufficient rest or sleep during each of the preceding 30 days is 9.0%, while this proportion is 9.5% for Oregon residents. These data are based on simple random samples of 11,548 California and 4,681 Oregon 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 PCA - POR. Round your answers to two decimal places.) Before calculating the interval, we should check that the conditions are satisfied. The sample is V random and the sample represents [less than 10% of all California and Oregon.residents.Therefore whether or not one person in the sample reported insufficient rest or sleep is independent of another. The success-failure condition is Vy met since the number of successes and failures is [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 1 %.
