Students enrolled in an introductory statistics course at a university were asked to take a survey that indicated whether the student has a visual or verbal learning style. Of the 39 students who took the survey, 25 were judged to have a visual learning style and 14 were considered verbal learners.
-How would a $99 \%$ confidence interval compare to this one in terms of its midpoint and half-width? (Do not bother to determine this interval.)

The Answer is A

99 \%

confidence interval would have the same midpoint (.641) as the

90 \%

confidence interval, but it would have a larger half-width because the

z^{*}

value used to create the

99 \%

interval would be greater than 1.645 .
