(6.24 Sleep deprivation, CA vs. OR, Part II). Exercise 6.22 provides data on sleep deprivation rates of Californians and Oregonians. The proportion of Cali- fornia residents who reported insufficient rest or sleep during each of the preced- ing 30 days is 8.0%, while this proportion is 8.8% for Oregon residents. These data are based on simple random samples of 11,545 California and 4,691 Oregon residents. Conduct a hypothesis test to determine if these data provide strong evidence the proportion with sleep deprivation is different for the two states.
