The average annual tuition for a public university in 1998 was
$19,599. In 2018, the average annual tuition for a public
university is $26,758.
How much (as a percentage) has the tuition cost increase on
average per year?
State your answer to two decimal places (e.g., 3.86)

The average annual tuition and fees at public 4-year
institutions in the US in 2004 was $13,576 and in 2014 was $18,231.
Let y be the average tuition and fees in the year x, where x = 0
represents the year 2004.
a) Write a linear equation that models the growth in average
tuition and fees at public 4-year institutions in the US in terms
of the year x.
b) Use this equation to predict the average tuition and fees...

The average annual cost (including tuition, room, board, books,
and fees) to attend a public college takes nearly a third of the
annual income of a typical family with college-age children.† At
private colleges, the average annual cost is equal to about 60% of
the typical family's income. The following random samples show the
annual cost of attending private and public colleges. Data are in
thousands of dollars.

A public university recently raised tuition in order to
supplement the reduction in budget provided by the state. One
semester after the tuition increase, a student organization
contacted randomly selected students and asked whether the tuition
increase was justifiable. The total number of responses was 250, of
which 130 was “yes”. Test the hypothesis that more than half of the
students felt the tuition increase was justifiable. Use level of
significance alpha= 0.05. Write down the hypotheses: H_0: H_1: The...
How much has the price of housing increased on average per year over the time period in percentage terms?

The mean annual tuition and fees in the 2018 - 2019 academic
year for a sample of 14 public colleges in California was $30,500
with a standard deviation of $4,500. At the α = 0.01 level
of significance, can you conclude that the mean tuition and fees
for public institutions in California differs from $30,000?
1. State the null and alternative hypotheses and the type of
test this is?
2. Compute the critical value and the value of the test...

In 1975 the price of a new house was $51,870. In 2020 the price
of a new house is $198,817. How much has the price of housing
increased on average per year over the time period in percentage
terms? State your answer to two decimal places (e.g., 4.76)

It is claimed that the average cost of tuition and fees at a
four-year public college is greater than $5500. The standard
deviation of college tuitions is known to be $659, and the mean
tuition and fees of a sample of 36 schools is computed to be
$5900.
a. Is this a two-tailed, right-tailed, or left-tailed test?
b. What is H1?
c. What is the test value?
d. Verify or deny the claim with 90% certainty.

In the public schools in Massachusetts, the average number of
students per computer for the 2007–2008 school year was 3.1 with a
standard deviation of 1.1. A random sample of 42 public schools in
the state of Massachusetts was obtained last year.
Determine the mean (in students per computer) of the sampling
distribution of the sample mean.
