Florida County Data Set. The dataset described in Appendix C.4 contains infant mortality rates for 20142016 for each county in Florida. Test for an association between infant mortality rates and the independent variables relating to county median income and percent with no high school degree. Note that some counties are extremely small. A reasonable model for number of deaths is a Poisson with mean = k
 (number of births), for some unknown constant k. Use the properties of the Poisson to suggest a sensible way to weight the mortality rates (= 1000
 number of deaths /number of births).
