A programmer plans to develop a new software system. In planning for the operating system that he will use, he needs to estimate the percentage of computers that use a new operating system. How many computers must be surveyed in order to be 90% confident that his estimate is in error by no more than three percentage points? a) Assume that nothing is known about the percentage of computers with new operating systems. n= b) Assume that a recent survey suggests that about 91% of computers use a new operating system. n=
