A new screening test for West Nile Virus is developed for use in the general population. The sensitivity and specificity of the
morpeh [17]

The predictive value of a positive test is is 0.43.

------------------

This question is solved using the concepts of sensitivity and specificity.

  • Sensitivity: It is the true negative rate, that is, the proportion of people without the disease that test negative.
  • Specificity: It is the true positive rate, that is, the proportion of people with the disease that test positive.

------------------

  • Sensitivity of 60% means that of the 100 - 10 = 90% of people without the disease, 60% test negative and 100 - 60 = 40% test positive.
  • Specificity of 70% means that of the 10% with the disease, 70% test positive.

------------------

The predictive value of a positive test is:

Probability of a positive test, which is 40% of 90% plus 70% of 10%, so:

p = 0.4\times0.9 + 0.7\times0.1 = 0.43

The predictive value of a positive test is is 0.43.

3. Given the following similar triangles. Find the values of variables and label all the unknown angles
astraxan [27]

Answer:

The answer to your question is x = 6 and y = 9

Step-by-step explanation:

Data

AB = x                     DF = 18

BC = 5                     FE = 15

AC = 3                     DE = y

Process

1.- Find y

Use proportions to find it

                 DE/FE = AC/BC

Substitution

                 y/15 = 3/5

Solve for y

                  y = 15(3/5)

                  y = 45/5

                  y = 9

2.- Find x

                AB/DF = BC/FE

Substitution

                x/18 = 5/15

Solve for x

                x = 18(5/15)

                x = 90/15

                x = 6
