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 99% confident that his estimate is in error by no more than three percentage points? Complete parts (a) through (c) below. Question content area bottom Part 1 a) Assume that nothing is known about the percentage of computers with new operating systems. n=enter your response here (Round up to the nearest integer.) Part 2 b) Assume that a recent survey suggests that about 90% of computers use a new operating system. n=enter your response here (Round up to the nearest integer.) Part 3
