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 manyr computers must be surveyed in order to be 95% condent that his estimate is in eer by no more than one percentage point? Complete parts (a) through (c) below. E) a] Assume that nothing is known about the percerltage of computers with new operating systems. n=o (Round up to the nearest integer.) bi Assume that a recent survey suggests that about 96% of computers use a new operating system. n 2 (Round up to the nearest integer} c] Does the additional survey inlorrnation from part (b) have much of an effect on the sample size that is required? 0 A. No, using the additional survey information from part (b) only slightly increases the sample size. 0 B. No, using the additional survey information from part (b) does not change the sample size. 0 C. Yes, using the additional survey information from part {b} dramatically reduces the sample size. 0 D. Yes, using the additional survey inlonnation from part {b} dramatically increases the sample size
