Crosstabs Z-test interpretation

Michelle-2
Hi, I'm having trouble interpreting the following output with regard to the
z-test/proportion output- would someone be willing to give me some feedback?

Or, do you know of a better way to test the significance of the
proportion/percent of a nominal DV on levels of a nominal IV ?

THANK YOU!!!
