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 0.02margin of error and use a confidence level of 95​%. Complete parts​ (a) through​ (b) below. a. Assume that nothing is known about the percentage to be estimated.   n=   b. Assume prior studies have shown that about 55​%of​ full-time students earn​ bachelor's degrees in four years or less.   n=
