We have everything necessary to determine the number of sales calls, n, Lori made. Substitute the known values o- = 0.05 and p = 0.50 into the formula below. n = p(1 - p) 0.50 (1 - 0,50) If Lori obtains a book adoption on 50% of her sales calls and has a standard error of 0.05, she made sales calls.
