i want to comapre the death ratio among 4 different groups which has
different health conditions,
so my data set looks like this,

type of condition           death ratio
1                                 6 out of 37 (16.2%)
2                                 3 out of 30 (10%)
3                                 1 out of 9   (11.1%)
4                                  2 out of 26 (7.7%)

so now i wanna do a stats test to see if the death ratios are the same
for the 4 types of condition,
but since there is only one observation for each type, i'm not sure
which analysis i should use.
please help, many thanks!
