Is point prevalence a proportion?
A. Yes
B. No - ANSWER A. Yes
Point Prevalence is the PROPORTION of a population that has the characteristic at a
specific point in time.
Suppose 13 people from a population of size 406,245 had a particular disease at time t.
What is the point prevalence of this disease at time t? - ANSWER Poi P = C / N
Poi P = ,245
Poi P = 0.00003200039385
Poi P ≈ 0.000032 or 0.0032%
Which of the following expressions is equivalent to the point prevalence estimate of
0.000032?
A. 3.2 per 1,000
B. 3.2 per 100,000
C. 32 per 100,000 - ANSWER B. 3.2 per 100,000
A study was formed to keep track of the population and deaths in Rateboro in 1980. It
records several age groups, with participants ranging from 18 years old to over 75
years of age, genders, and the rates. It was then recorded with the totals from the U.S.
population.
A hypothetical data was constructed. The table has the following components.
