Lori Jeffrey is a successful sales representative for a major publisher of college textbooks. Historically, Lori obtains a book adoption on 36% of her sales calls. Viewing her sales calls for one month as a sample of all possible sales calls, assume that a statistical analysis of the data yields a standard error of the proportion of 0.08. (a) How large was the sample used in this analysis? That is, how many sales calls did Lori make during the month? (c) Using the sampling distribution of p, compute the probability that Lori will obtain book adoptions on 46% or more of her sales calls during a one-month period. (Round your answer to four decimal places.)

The mgf of the Poisson(A) distribution takes the form m(t) = exp{A(e' – 1)} teR. Also, if Y is a random variable with mgf my (t), and X = aY + b is a transformed version of Y, then the mgf for X takes the form mx(t) = ebmy (at).
