Hi! I'm super stuck on this statistics question and could really use some help. I only need help on option b, entailing 45% of fulltime students earn bachelor's degrrees in four years or less. Thank you so much in advance!

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 n 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 95%. Complete parts (a) through (c) below. a. Assume that nothing is known about the percentage to be estimated. 1 = 9604 {Round up to the nearest integer.) b. Assume prior studies have shown that about 45% of full-time students earn bachelor's degrees in four years or less. n=j {Round up to the nearest integer.)
