Find the sample size needed to estimate that percentage. Use a 0.01 margin of error and use a confidence level of 90%. Complete parts (a) through (c) below. a. assume that nothing is known about the percentage to be estimated. n=___? (round up to the nearest interger) b. assume prior students earn bachelor's degrees in four years or less. n=____? (round up to the nearest interger) c. Does the added knowledge in part b have much of an effect on the sample size? a. No, using the additional survey information from part b only slightly reduces the sample size. b. Yes, using the additional survey information from part b only slightly increases the sample size. c. Yes, using the additonal survey information from part b dramatically reduces the sample size.. d. No, using the additional survey information from part b does not change the sample size thank you, if you use stat crunch, can you please include the command steps?
