Answer:

12/15 of the way

Step-by-step explanation:

create a proportion of time/filled = time/filled

let 'x' = fractional portion of filled pool

1/2÷1/15 = 6÷x

complex fraction 1/2÷1/15 is the same as 1/2 × 15/1 and this is 15/2

15/2 = 6/x

cross-multiply to get:

15x = 12

x = 12/15

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.
