association between year and age for the poisonings at the .05 level (

C) Within each age group, 0-5, 6-59 (put two 6-19 and 20-59 together to get enough data), and 60
and up, run the Poisson difference tests we discussed to see if there are any interesting
differences across the years. There will be 3 comparisons pre age group times 3 groups for 9
tests, Use FDR, not independent at the Q value of .1 to evaluate.
D) What about the approach in C means some of the P values are not independent?
