In a population of 14,000, there were 500 who had pneumonia at
the end of 2012. A total of 160 new cases were diagnosed in
2013. What is the 1-year cumulative incidence of
pneumonia?
a.1.14% b.1.14% over 1 year c.1.19% d.1.19% over 1 year
If the RR=2.3 and the 95% CI (2.0, 2.8), then one can conclude
that: (X)
a. The results are statistically significant because 1 is not in
the interval
b. The results are not statistically significant because 2.3 is
in the interval
c. The results are statistically significant because 2.3 is in
the interval
d. The results are statistically significant because 0 is not in
the interval
