You are monitoring Alzheimer’s disease in your state. You come across a state report from last year that shows a proportionate mortality rate of 1.87 percent due to Alzheimer’s disease. Your state population is 3,170,000. Of that population, 30,000 people were living with diagnosed Alzheimer’s. If there were 21,270 total deaths in your state last year, how many of those deaths occurred because of Alzheimer’s disease? Group of answer choices 398 59,279 561 8,730 None of the above. You cannot determine the number of deaths with the information given.

398 deaths were caused by Alzheimer.

Explanation:

Proportionate mortality rate (PMR) gives the proportion of deaths in a given population over a period of time, this can be linked to various causes.

Mathematically PMR is reoresented below;

PMR =   X 100

where =  No. of death from a specific cause (In our case Alzheimier )

          = Total No. of death at a given period

from the question the parameters were given except the number of death from Alzheimier

1.87 =

multiply both side by 21,270 to isolate

= 1.87 x 21,270

Divide both side by 100 to obtain  

  =

= 397.749

since dead people can not be divided
