Q3 Hw 4

by Laura Koth -

my study group and I are completely stuck on completing the table below. we either don't think we have enough information to complete it or there must be assumptions that we aren't appreciating to complete it.

I may not be able to make it to OH due to computer issues, so can you help us with what is the "big picture" to what you want us to understand about this question or can you elaborate on the assumptions we must make to complete the table?

 thank you

Hi Laura,

this question does not ask you for any calculations. It just asks you to rearrange the table, incorporating now 2 index tests (B and T), which increases the possible combinations from a 2x2 table to a  2x4 table (given). The assumption that you might have missed is that T is perfect, i.e all T+ are D+ and all T- are D-.

Does that help?
