Question

The table shows the leading causes of death in a certain country in a recent year. The population of the country was 313 million. What is the empirical probability of death by stroke during a single year? How much greater is the risk of death by stroke than death by kidney disease? Cause Heart disease Cancer Chronic respiratory diseases Stroke Accidents Deaths 596,400 575,200 143,500 128.400 122,300 Cause Alzheimer's disease Diabetes Pneumonia/Influenza Kidney disease Suicide Deaths 84,400 73.400 53,300 45,700 38.600 . The empirical probability of death by stroke during a single year is (Round to five decimal places as needed.) The risk of death by stroke is about times greater than risk by death of kidney disease. (Round to one decimal place as needed.)

Answer 1

a)

We can get the value of probability by dividing no of death by strokes to the total number of deaths which is 1861,200

128, 400 P(death by stroke in a year) = 1,861.200 = 0.0690

P(Kidney)

45, 700 P(kidney) = 1861.200 1.861 200 = 0.0246

The risk of death by stroke is 6.90% and the risk of death by kidney disease is 2.46%, thus the risk of death by stroke is

6.90 = 2.80 2.46

times greater than the risk of death by kidney disease.
