Quizplus · Accepted Answer

The question is asking for the age at which 13.21% of Canadian males have died. This means we need to find the age that represents the 13.21th percentile in the distribution of ages at death for Canadian males. Based on life expectancy data, we know that Canadian males have a life expectancy of approximately 80 years. Therefore, the midpoint of the distribution would be around age 40 (i.e. halfway between 0 and 80). Since 13.21% is less than 50%, we know that the age we are looking for is below the midpoint. Looking at the answer choices, we see that D) 65 years is the only one below the midpoint and is therefore the best choice.
