In order to estimate the proportion of students on a particular
campus who favor a campus-wide ban on alcohol, a social researcher
interviewed a random sample of 100 students from the college
population. She found that 36% of the sample favored banning
alcohol. (9 points)
a) Find the mean of the sampling distribution of proportions
(µp).
b) Find the standard error of the proportion (σp).
c) Find the estimated standard error of the proportion
(sp).

A university is interested in whether there's a difference
between students who live on campus and students who live off
campus with respect to absenteeism. Over one semester, researchers
take random samples of on-campus and off-campus students and record
the following number of classes each student misses.
On-campus: (3, 4, 0, 6, 2, 1, 3, 3, 5, 2, 4, 4, 6, 5, 2)
Off-campus: (6, 5, 2, 6, 2, 0, 7, 8, 1, 7, 2, 6, 5, 3, 2)

Some five courses are offered on campus in a semester. The group
of students who take at least one of these courses consists of 155
students. There are 80 students registered in each course. For any
two among these courses, there are precisely 40 students who take
both of them. For any three of these courses, there are precisely
20 students who take all three of them. For any four among these
courses, there are precisely 10 students who take...

This policy ensures that all students in grades one to nine are
physically active for at least thirty minutes each day through
activities organized by the school (Alberta, 2020). Being active is
being healthy. As was mentioned in the Dr. Christine Kennedy’s
article schools have the potential to help children develop
lifelong, healthy eating patterns and encourage physical activity;
research supports school-based interventions to increase physical
activity and decrease obesity (Kennedy, 2010).
Giving the kids an opportunity to have an...

Jane wants to estimate the proportion of students on her campus
who eat cauliflower. After surveying 17 students, she finds 2 who
eat cauliflower. Obtain and interpret a 95% confidence interval
for the proportion of students who eat cauliflower on Jane's
campus using Agresti and Coull's method.

Students and faculty alike are concerned about the cost
of textbooks. A committee of both students and faculty searched the
internet for appropriate books that would be available for less
than $60. A random sample of 40 texts gave a mean of $65.12 with a
standard deviation of $23.08. At the 5% level of significance, do
the texts selected in the sample cost significantly more than the
amount the committee considered appropriate?
