Dear listers
I am a very newbie with graphs in R. I have a pulmonary function prediction
equation in the form of PVC = 1.1 - 0.45*age in years + 0.011*height in cm.

Thanks in advance.

When using the z-test between proportions in two different groups, or using
chi-squared to test the null hypothesis of equal proportions of two or more
groups, the null hypothesis is that
H0: p1=p2=p3.....=p
where this p is the pooled proportion, the proportion in the summed groups =
n1+n2+n3+..../N1+N2+N3....
in the z-test between two
