let x have a binomial distribution with parameters n = 25 and p. calculate each of the following probabilites using the normal approximation (without continuity correction) for the cases p = .5, .8) and compare to the exact proabilities calculated from the bionomial distribution appendix. http://onlinepubs.trb.org/onlinepubs/nchrp/cd-22/manual/v2appendixc.pdf (link to the appendix)
