For a valid result the following conditions are suggested ; X ~ B(n,p) np > 5 and n(1-p) > 5 (ie p is close to ½ or n is large) WebThe first inequality should lead to p<=0.8 but in the context of the question that doesn't make sense, and would therefore lead to p=0.5 (2 options per question) and n=40 which gives s.d. of 10. Anyway, maybe I'm missing something more obvious but I …
