A sample of 35 two-year colleges in 2012-2013 had a mean
tuition (for in-state undergraduate students) of $2918. The true
standard deviation of the tuition for these schools is known to be
$1079.
Calculate a 90% confidence interval for the average in-state
tuition of all two-year colleges in 2012-2013.

In a study about undergraduate student credit card usage, it was
reported that undergraduate students have a mean credit card
balance of $3173 (Sallie Mae, April 2009). This figure was an
all-time high and had increased 44% over the previous five years.
Assume that a current study is being conducted to determine if it
can be concluded that the mean credit card balance for
undergraduate students has continued to increase compared to the
April 2009 report. Based on previous studies,...

Big State U charges in-state and out-of-state students different
tuition rates. In-state students pay $2,000 a term and respond
according to the following demand equation:
Q1 = 25.000 - 3T i
Where Qi is in-state student enrollment and Ti is in-state
tuition. Out-of-state students pay $4,500 a term and their demand
is:
Qo = 45000 - 8To
WHere Qo is out-of-state enrollment and To is out-of-state
tuition.

A paper described a survey of 495 undergraduate students at a
state university in the southwestern region of the United States.
Each student in the sample was classified according to class
standing (freshman, sophomore, junior, or senior) and body art
category (body piercings only, tattoos only, both tattoos and body
piercings, no body art).
Use the data in the accompanying table to determine if there is
evidence that there is an association between class standing and
response to the body...

In the past, 60 % of all undergraduate students enrolled at
state university earned their degrees within four years of
matriculation. a random sample of 95 students from the class that
matriculated in the fall of 2012 was recently selected to test
whether there has been a change in the proportion of students who
graduate within four years. Administrators found that 40 of these
95 students graduated in the spring of 2016 (i,e. , four academic
years after matriculation) ....
