Please, if someone could please help me with this problem... If np ≥ 5 and nq ≥ 5, estimate P (more than 4) with n = 11 and p = 0.7 by using the normal distribution as an approximation to the binomial distribution; if np < 5 or nq < 5, then state that the normal approximation is not suitable. a. P(more than 4) = b. The normal distribution cannot be used.

    is 3.3 between 3 and 4 ? if so, then how is 3 or 4 (or anything between them) bigger than 5 ?

    so 3.3 is less than 5 what do we do if np or nq is less than 5 ?
