Answer:
The equation for the relationship is .
Step-by-step explanation:
Given that point is part of a direct relationship. That is:
(1)
Where is the proportionality constant.
If we know that and
, then the proportionality constant is:
Lastly, the equation for the relationship is .
Answer:
The probability that the result is positive is P=0.04475=4.475%.
Step-by-step explanation:
We have the events:
D: disease present
ND: disease not present
P: test positive
F: test false
Then, the information we have is:
P(D)=0.005
P(P | D)=0.99
P(P | ND)=0.04
The total amount of positive test are the sum of the positive when the disease is present and the false positives (positive tests when the disease is not present).
The probability that the result is positive is P=0.04475.
