In a study of government financial aid for college students, it becomes necessary to estimate the percentage of full-time college students who earn a bachelor's degree in four years or less. Find the sample size needed to estimate that percentage. Use a 0.02 margin of error and use a confidence level of 95%. Complete parts (a) through (c) below. se set sef pa a. Assume that nothing is known about the percentage to be estimated. see n= (Round up to the nearest integer.) b. Assume prior studies have shown that about 40% of full-time students earn bachelor's degrees in four years or less. n= (Round up to theurearest integer.) c. Does the added knowledge in part (b) have much of an effect on the sample size? O A. No, using the additional survey information from part (b) does not change 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) only slightly reduces the sample size O D. Yes, using the additional survey information from part (b) only slightly increases the sample size
