base data: only average proportions and sample sizes,

issue: comparing specifical mortality in 8clusters with county

chosen test: chi-square of proportions via contingency tables

alpha=0,05

problem:

cluster1 cluster8 county

proportion in % 0,413 0,241 0,287

n 5104 64 000 557 613

p-value 0,095 0,038

so cluster8 unequal, cluster1 equal, despite the average proportions..

any better test? or just take it as it is? browsed google for two hours, no idea..

just repeating - base data - I have only average proportions and sample sizes, for each cluster and county..

thanks..

P.S. tried even z-test but p-values are quite all around zero..
