Kishore et al. state that the average mortality rate between September 20 and December 31, 2016 was 8.82 deaths per 1,000 people. They estimated that the average mortality rate during these same months in 2017 was 14.31 deaths per 1,000 people. a. Calculate the incidence rate difference for mortality, comparing 2017 data to 2016 data. Round your answer to the second decimal place. (4 points)
b. Interpret the incidence rate difference obtained in Question 4a. (4 points)
