smaller margins of error.
C) For a fixed margin of error, larger samples provide
greater confidence.
D) For a given confidence level, halving the margin of error

F) For a certain confidence level, you can get a smaller
margin of error by selecting a bigger sample.
G) For a fixed margin of error, smaller samples will mean
lower confidence.
H) For a given confidence level, a sample 9 times as large
will make a margin of error one third as big.
13) According to a recent study, 74% of college
freshmen returned to college the next year. To
keep the margin of error at most 3%, how many
adults must be surveyed to obtain a 97%
confidence?
