The administration at your college wants to find out the proportion of students receiving some kind of financial aid. He selects records of 200 randomly selected students and found only 152of them are receiving financial aid then . 99% confidence interval to estimate the true proportion of student receiving financial aid is . O 0.4221, 0.6179 O 0.68221, 083779 O cannot be determined O 0.5210, 0.7228 O 0.6215, 0.7579He wants to be 99% confidence that his data is reliable. In this case the margin of error E is O 0.98 O 0.129 O 0.257 O 1.96 O cannot be determinedA psychologist has developed a new test and wants to estimate mean score achieved by adult pilots. Assume that s = .25 He wants to be 95% condent that the sample mean must be accurate within 3% of the true mean score. In that case the sample size must be 0 cannot be determined 0 267 O 524 O 228 O 252
