In a study of government financial aid for college​ students, it becomes necessary to estimate the percentage of​ full-timecollege students who earn a​ bachelor's degree in four years or less. Find the sample size needed to estimate that percentage. Use a 0.05 margin of error and use a confidence level of 99​%.Complete parts​ (a) through​ (b) below. a) Assume that nothing is known about the percentage to be estimated. nequals nothing ​(Round up to the nearest​ integer.) b)Assume prior studies have shown that about 60​% of​ full-time students earn​ bachelor's degrees in four years or less.
