Question

Researchers estimate by the end of 2020, 850,000 new cases of heart disease and 275,000 heart disease deaths will be recorded in the United States. The estimated population of the United States at mid-point of 2020 is 341,672,244. Calculate the projected incidence rate of heart disease per 100,000 in the United States in 2020.

Answer 1

Answer:

249 per 100,000

Step-by-step explanation:

The projected incidence rate of heart disease per 100,000 in the United States in 2020 is determined by the number of estimated new cases of heart disease multiplied by 100,000 and divided by the estimated population of the United States in 2020:

$R=\frac{850,000*100,000}{341,672,244}=248.78$

Rounding up to the next whole unit, the projected incidence is 249 per 100,000.
