Exercise 6.22 provides data on sleep deprivation rates of Californians and Oregonians. The proportion of California residents who reported insucient rest or sleep during each of the preceding 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. a) Conduct a hypothesis test to determine if these data provide strong evidence the rate of sleep deprivation is different for the two states. (Reminder: Check conditions.) p value 1.65 and test statistic = 1.65 I am trying to figure out how they were able to get this answer.

are based on simple random samples of 11,545
California and 4, 691 Oregon residents. a) Conduct a
hypothesis test to determine if these data provide
strong evidence the rate of sleep deprivation is different
for the two states. (Reminder: Check conditions.) p
