14.33 Provide a two-sided 95% CI for incidence rate of flu among high-risk students during winter 2008−2009. Among 1200 students in one high school in the city, 200 developed a new case of influenza over the 90 days from December 21, 2009, to March 20, 2010. 14.34 What is the estimated incidence rate of flu in the 2009−2010 winter season per 1000 person-months? 14.35 Provide a 95% CI for the rate estimated in Problem 14.34. 14.36 Test the hypothesis that the rate of flu has changed from the 2008−2009 to 2009−2010 winter season. Report a two-tailed p-value
Suppose the incidence rate of influenza (flu) during the win-ter of 2008−2009 (i.e., from December 21, 2008, to March 20, 2009) was 50
14.32 A group of high-risk high school students was iden-tified in the winter of 2008−2009 who had 3+ previous episodes of influenza before December 21, 2008. There were 20 students in this group, each followed for 90 days, of whom 8 developed influenza. Test the hypothesis that the high-risk students had a higher incidence rate of influenza than the average high school student during the winter of 2008−2009. Report a one-tailed p-value.
14.33 Provide a two-sided 95% CI for incidence rate of flu among high-risk students during winter 2008−2009. Among 1200 students in one high school in the city, 200 developed a new case of influenza over the 90 days from December 21, 2009, to March 20, 2010.
14.34 What is the estimated incidence rate of flu in the 2009−2010 winter season per 1000 person-months?
14.35 Provide a 95% CI for the rate estimated in Problem 14.34.
14.36 Test the hypothesis that the rate of flu has changed from the 2008−2009 to 2009−2010 winter season. Report a two-tailed p-value
