Refer to the National Highway Traffic Safety Administration (NHTSA) study of fatal auto accidents caused by air bags, Exercise 5.30

(p. 285). Recall that the NHTSA wants to estimate the proportion of such accidents in which children seated on the front passenger side were killed. How many fatal accidents should the NHTSA sample in order to estimate the proportion to within .1 of its true value using a 99%

confidence interval?
