A small publisher wishes to publish self-improvement books.  After a survey of the market, the publisher finds that the mean cost of the type of book that she wishes to publish is $15.00.  If she wants to price her books to sell in the middle 34% range, what should the maximum and minimum prices of the books be?  The standard deviation is $0.25 and the self-improvement books are normally distributed.     If there are TI-83 functions I would prefer to see it answered with TI-83 and also manually.  thank you
