A country has a population of 62 million. (a) Last year, there were 23,085 traffic fatalities. Find the fatality rate in deaths per 100,000 population. (b) The leading causes of death are shown in the table below along with the actual number of deaths.. The capital city is home to 2.5 million people. About how many people would you expect to have died of stroke in the capital? Cause Heart disease Cancer AIDS Stroke Pulmonary disease Number of 147,600 92,250 52,890 34,400 27,160 deaths (c) The overall birth rate is 14.6 births per 1000. The overall death rate is 8.1 deaths per 1000. Based on births and deaths alone (not counting immigration), estimate the change in the population in the next year if the rates stay the same.arrow_forward
