A national survey of asthma conducted on May 1, 2012, obtained the following results for the state of Oklahoma:

X = The number of residents with asthma
Y = The population of the state on June 30, 2012, and all members of the population were considered at risk
Z = The number of new cases of asthma diagnosed during 2012.

The incidence rate of asthma during 2012 (per 100,000) would be expressed as:

Respuesta :

Answer:

The incidence rate per 100,000 = [tex]\frac{\textup{Z}}{\textup{Y}}\times100,000[/tex]

Step-by-step explanation:

Data provided:

The number of residents with asthma = X

The population of the state on June 30, 2012 = Y

The number of new cases of asthma diagnosed during 2012 = Z

Now,

The incidence rate is the rate or then frequency at which a disease occurs over a time period

Therefore,

In the given question

The incidence rate per 100,000 = [tex]\frac{\textup{number of new cases of asthma diagnosed during 2012}}{\textup{The population of the state on June 30, 2012}}\times100,000[/tex]

or

The incidence rate per 100,000 = [tex]\frac{\textup{Z}}{\textup{Y}}\times100,000[/tex]
