Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

2.4 Table 2.10 shows fatality results for drivers and passengers in auto accidents in
Florida in 2008, according to whether the person was wearing a seat belt.
a. Estimate the probability of fatality, conditional on seat-belt use in category (i) no
and (ii) yes.
b. Estimate the probability of wearing a seat belt, conditional on the injury being (i)
fatal and (ii) nonfatal.
c. For the most natural choice of response variable, find and interpret the difference
of proportions, relative risk, and odds ratio. Why are the relative risk and odds
ratio approximately equal?
