How many computers must be surveyed in order to be99%confident that his estimate is in error by no more thantwo percentagepoints? 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 operatingsystem. How many computers must be surveyed in order to be 99% confident that his estimate is in error by no more than two percentage points? Complete parts (a) through (c) below.a) Assume that nothing is known about the percentage of computers with new operating systems.n:%3D(Round up to the nearest integer.)b) Assume that a recent survey suggests that about 89% of computers use a new operating system.n=|(Round up to the nearest integer.)c) Does the additional survey information from part (b) have much of an effect on the sample size that is required?O A. No, using the additional survey information from part (b) only slightly increases the sample size.O B. Yes, using the additional survey information from part (b) dramatically reduces the sample size.O C. No, using the additional survey information from part (b) does not change the sample size.O D. Yes, using the additional survey information from part (b) dramatically increases the sample size.liels t
