Acertain disease has an incidence rate of 0.4%. if the false negative rate is 7% and the false positive rate is 5%, compute the probability that a person who tests positive actually has the disease.

The incidence rate is = 0.4%  or 0.004

The false negative rate is = 7%  or 0.007

The false positive rate is = 5%  or 0.005

The probability is

0.05*(1-0.004) + 0.95*0.004

= 0.0498 + 0.0038 = 0.0536

Probability that a person who tests positive actually has the disease would be represented as:

Let the probability be represented by = p

p * 0.0536 = 0.95 * 0.004

p = 0.0038/0.0536

p = 0.0708

Hence, probability is 0.0708

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
