- During the 2017-2018 flu season, a random sample of 180 hospitalizations related to flu was studied. It was later determined that 19 patients have died. A similar study during the 2018-2019 flu season revealed that in a random sample of 180 hospitalized cases related to flu, there were 16 deaths observed. At 5% significance level, test the claim that the percentage of deaths in 2017-2018 is greater than the percentage of deaths in the 2018-2019 season.
