Answer:
a) 0.9548
b) 0.0452
Step-by-step explanation:
Specificity of test:
The specificity of a test is the true negative rate, that is, the proportion of people without the disease that test negative.
Sensitivity of test:
The sensitivity of a test is the true positive rate, which is the proportion of people with the disease that test positive.
a. What proportion of the people who test positive for Malaria would we expect to actually have the disease?
This is the sensitivity of the test, which is of 95.48%, so the proportion if 0.9548.
b. What proportion of people who test positive for Malaria will not have the disease?
True positive rate is of 95.48%.
1 - 0.9548 = 0.0452
So the proportion of people who test positive for Malaria will not have the disease is 0.0452.

Answer:
The answer to your question is the letter A.
Step-by-step explanation:
Data
radius = 12 ft
Circumference = ?
Process
The Circumference is the length of the border of a circle. To find the length of this border, just use the formula, substitute the radius and pi and simplify.
Formula
Circumference = 2πr
Substitution
Circumference = 2(3.14)(12)
Simplification
Circumference = 75.36 cm
