Two group of people. all people in G1 is in a health plan, and these in G2
G1 have x1 member, and y1 hospital admits. hospital admit rate is
G2 has x2 member and y1 hospital admits. hospital admit rate is h21=y2/x2
I want to test if there is significant difference between G1 and G2.
What kind test should I use?
