Question

In 2008, 565,650 americans died of (all forms of) cancer. assuming a population of 305 million, what was the mortality rate in units of death per 100,000 units

Answer 1

The cancer mortality rate in the United States for the year 2008 was calculated to be approximately 185.41 deaths per 100,000 individuals.

Step-by-step explanation:

The student is tasked with calculating the mortality rate of cancer in the United States using the given statistics from 2008. To find the mortality rate per 100,000 people, we need to use the death count and the population size to create a ratio that reflects the number of deaths per 100,000 individuals.

To calculate the mortality rate:

1. First, we find the rate for the actual population by dividing the number of deaths by the population size: Mortality Rate = Number of deaths / Population size.
2. Then, we normalize this rate to reflect the number of deaths per 100,000 people by multiplying the calculated rate by 100,000: Normalized Mortality Rate = (Mortality Rate × 100,000).

Using the provided numbers: 565,650 deaths among a population of 305 million, the calculation is as follows:

Mortality Rate = 565,650 / 305,000,000

Mortality Rate = 0.0018541 (this is the rate for the actual population)

Then we normalize to per 100,000:

Normalized Mortality Rate = 0.0018541 × 100,000

Normalized Mortality Rate = 185.41 deaths per 100,000 people.

Therefore, in 2008 the cancer mortality rate in the United States was 185.41 deaths per 100,000 individuals.

Answer 2

There were 565,650 deaths in a population of 305 million.

Note that
305 million =\ 305 x 10⁶
100,000 = 10⁵

By proportion, the deaths per 100,000 is

`(10^(5))/(305 * 10^(6)) (565,650) = 185.46`

Answer: 185 per 100,000 units
