1-How would you define Incidence Rate?

2-A doctor’s office gives each patient a survey to complete. The results of the survey revealed that a person can suffer from allergic flare-ups up to 3 times per year with each flare-up lasting one week. Find the incidence rate for anyone in the population who suffers from allergies.

3-Calculate infant mortality rate in Massachusetts for 2010, providing there were 10 infant deaths for every 1500 live births.

4-In 2011 there were 14 infant deaths for every 1000 live births; in 2012 there were 12 infant deaths for every 1300 live births. Using the infant death information from problem 3, calculate the infant mortality rate over the 3 year period.

5-In an independent study in the county of Worcester, 18 males die from liver cancer per 100, 000 males. With a standard error of 3.7, what is the relative standard error?

Solution

1) the risk of developing a particular disease during a given period of time; the numerator of the rate is the number of
newcases during the specified time period and the denominator is the population at risk during the period...

Incidence rate = number of new cases of a disease occurring in the population during a specified period time / number of persons exposed to risk of developing the disease during that period of time

2) = 2 / 1 * 100% = 200%..

3) imr = 10*1000 / 1500 =6.67......( per 1000 live births)

4) imr for 2010 = 6.67

imr for 2011 = 14...
imr for 2012 = 12 * 1000 / 1300 = 9.23..
imr over 3 year period = ( 6.67 + 14 + 9.23 ) / 3 = 9.966667 ( per 1000 live births)

5) RSE = 100 * 3.7 / 18 = 20.5556 %...
