Screening tests (e.g., AIDS testing) are evaluated on the probability of a false negative or a false positive, and both of these are:
a. conditional probabilities
b. probability of the intersection of two events
c. probability of the union of two events
d. marginal probabilities
e. probability of dependent events
Question 2
A chi-square test of independence with 10 degrees of freedom results in a test statistic of 19.25 . Using the chi-square table, the most accurate statement that can be made about the p-value for this test is that:
a. p-value < 0.025.
b. 0.025 < p-value < 0.05.
c. 0.05 < p-value < 0.10.
d. 0.10 < p-value < 0.20.
