WebDec 19, 2024 · The criteria for using a normal distribution to estimate a binomial thus addresses this problem by requiring BOTH n p AND n ( 1 − p) are greater than five. Again, this is a rule of thumb, but is effective and results in acceptable estimates of the binomial probability. 1 − [ p ( X = 0) + p ( X = 1) + p ( X = 2) + … + p ( X = 16)] = p ( X ... WebP(more than 6)= _____(Round to four decimal places as needed.) If np≥5 and nq≥ 5, estimate P(at least 10) with n=13 and p=0.6 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.
WebNice question! The plan is to use the definition of expected value, use the formula for the binomial distribution, and set up to use the binomial theorem in algebra in the final step. We have E(e^(tx)) = sum over all possible k of P(X=k)e^(tk) = sum k from 0 to n of p^k (1-p)^(n-k) (n choose k) e^(tk)
