Can this be true? Why aren??t there decimal points? Is there a way to
find out the exact p-value?
The p-values are rounded, and of course they are not exac
Because your test statistics (z=-9.16) is too small. (well, z> 1.96 or
Z < -1.96 is p=0.05)
If you really want the exact p, you can try
pnorm(-9.16)
if I were you I will quote p<0.001 as well as the test statistics. (if
you are going to submit it to medical journals)
