In a study of government nancial 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 0.01 margin of error and use a condence level of 90%. Complete parts (a) through (c) below. 3. Assume that nothing is known about the percentage to be estimated. n = 6724 (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. n=o (Round up to the nearest integer.)
