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 0.03 margin of error and use a confidence level of 99%.
Complete parts (a) through (c) below.
a. Assume that nothing is known about the percentage to be estimated.
N=1844
(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. (Round up to the nearest integer.)
Given : Margin of error=E=0.03
Signifiacnce level=
From standard normal distribution table ,
a) Since , there is nothing to know the estimate of percentage
Therefore , assume that p=q=0.5
Therefore , the required sample size is ,
b) Since , p=0.40 , q=1-p=0.60
Therefore , the required sample size is ,

in a study of government financial aid for college students it becomes necessary to estimate the percentage of full-time college students to earn a bachelors degree in four years or less. find the sample size needed to estimate that percentage. use a 0.04 margin of error and use a confidence level of 99%.
In a study of government financial aid for college students, researchers needed to estimate the proportion of full-time college students who earn a bachelor's degree in 4 years or less. Assuming a confidence level of 90%, find the sample size needed to estimate that proportion with a 0.03 margin of error in two cases: (1) no assumptions are made about the value of the sample proportion, and (2) prior studies have shown that roughly 60% of full-time students earn a...
