This wording is straight from a problem I am attempting to solve, but I do not understand how to do it. I am not intending to submit a tutor's work as my own, I am requesting help in understanding how to work this problem.

"The Pap test has a notoriously low sensitivity. Let's now administer a second screen to those with positive Pap tests.The patient must be identified as positive by this second screen as well in order to be diagnosed.The second screen is a HPV DNA test for high risk strains of the virus.The sensitivity of the DNA test is 94.6% and the specificity is 94.1%.

Construct a 2x2 table for those 1134 who tested positive with the Pap test, and who will now undergo HPV DNA testing.Calculate both the net sensitivity and net specificity of these screens.Note that the net sensitivity is just the proportion of those with the condition that are classified as positive at the end of your algorithm.Similarly, the net specificity is the proportion of those without the condition that are classified as negative at the end of your algorithm.You do not need any specific formulas to calculate either."
