Answer:
a. 5.33% ( period: from "history" to the end of day, Jan 1, 2013
b. 66.67 per 1000, period, analysis after the whole year.
Step-by-step explanation:
Prevalence (point prevalence)
C= Number of current diagnosed cases as at Jan, 1 2013
T= Total population as at Jan, 1 2013...
Prevalence (point of prevalence ) is given by (C/T)*100
b. Incidence... Given by
Let N= new discovered cases after Jan 1 2013.
Incidence is given by
( C+N)/ T * 10^n... Where n degree of sampling
In this case, n= 3; 10^3= 1000...
Answer:
a).- Prevalence=5.33%
b).-Incidence during 2013=14 people
Step-by-step explanation:
Definition
Prevalence is the proportion of a population that has a specific characteristic in a given period.
For a representative sample, prevalence is the number of people in the sample with the characteristic of interest, divided by the total number of people in the sample.
The prevalence (expressed as a percent) on Jan 1, 2013 was
[tex]\frac{x}{y} prevalence=\frac{ Number of people in sample with characteristic}{Total Number of people in sample}[/tex]
In percent:
Prevalence=[tex]\frac{16}{300}[/tex] *100
Prevalence=5.33%
Incidence is a measure of the number of new cases of a characteristic that develops in a population in a specified period
the incidence during 2013 is
n=(300-16)=284 people on Jan 1, 2013
Incidendence during 2013=[tex]\frac{ new cases}{ people sample} = 4/284 *1000=14.08\\The answer is 14 people[/tex]
Answer=14 people
