Hey all,
My dataset consists of two variables, one categorical (survived/perished) one numerical (lengths of bone).
n (perished) = 24, n(survived) = 35, alpha=0.01 (for 99%CL).
It is asked for the critical value of survived and critical value of perished. The critical value is t (DF, alpha/2).
Table give me: t(23,0.005) = 2.8, t(34,0.005)~2.72
Now I tried to get the critical values in SAS and it worked out perfectly for the perished ones:
data perished;
set humerus;
if status='Perished';
run;
data perished;
tp=tinv (0.995,23);
run;
proc print data=perished;
run;
However, it didn't work out for the survived group and I can't figure out, why:
data survived;
set humerus;
if status='Survived';
run;
data survived;
ts=tinv (0.995;34);
run;
proc print data=survived;
run;
Log:
73 data survived;
74 ts=tinv (0.995;34);

Any ideas?!
