echnology to answer this question. Lori Jeffrey is a successful sales representative for a major publisher of college textbooks. Historically, Lori obtains a book adoption on 50% 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 0.05. (a) How large was the sample used in this analysis? That is, how many sales calls did Lori make during the month? (b) Let p indicate the sample proportion of book adoptions obtained during the month. Show the sampling distribution of p. (c) Using the sampling distribution of p, compute the probability that Lori will obtain book adoptions on 44% or more of her sales calls during a one-month period. Step 1 (a) How large was the sample used in this analysis? That is, how many sales calls did Lori make during the month? Let p be the population proportion of sales calls in which Lori obtains a book adoption. It is given that she gets a book adoption on 50% of her calls. Convert this percentage to a proportion. proportion = percentage 100% % P= 100%
