In a crossover trial involving 50 patients, two dialysis treatment schedules were compared.Ten patients complained of vomiting on both schedules, 30 on neither, nine on treatment A only and one on treatment B.

 

(a) What are the proportions of patients vomiting on each treatment?

 

(b) Perform a significance test comparing these two proportions and interpret the results.

For (a), I think it is 19/50 and 11/50

For (b), I think I have to use McNemar test: (19-11)^2/(19+11)=2.31.

But I'm not sure, can you please check if my answer is right.
