    Probability and statistics help

    Hey I was wondering if someone could double check my work on this problem:

    Consider a disease present in 1 in every 2 members of a population. A diagnostic test for this disease has sensitivity = specificity. Is it true that testing positive and having the disease are independent events? Justify.

    Given: P(D l +)

    I've double checked and triple checked and can confidently confirm that there's no work here to check.

    By the way, I doubt very much that testing positive and having the disease are independent events.
