Question

College tuition: The mean annual tuition and fees in the 2013-2014 academic year for a sample of 14 private colleges in California was $33,500 with a standard deviation of $7350. A dotplot shows that it is reasonable to assume that the population is approximately normal. Can you conclude that the mean tuition and fees for private institutions in California is less than $35,000? Use the a=0.10 level of significance and the P-value method with the TI-84 Plus calculator.

1) State the appropriate null and alternate hypotheses. H0=, H1= This hypothesis test is a (left tailed, right tailed or two tailed) test

2) Compute the P-value. Round the answer to four decimal places.

3) Determine whether to reject H0 (reject or not reject)

4) There (is or is not) enough evidence to conclude that the mean tuition and fees for private institutions is greater than $33,500.

Answer #1

(1)

- Null hypothesis (H
_{o}) : Mean tuition and fees for private institutions in california is $35000 that is**μ**= $35000 - Alternative Hypothesis (H
_{1}) : Mean tuition and fees for private institutions in california is less than $35000 that is**μ**< $35000 (left tailed.)

The mean annual tuition and fees in the 2013-2014
academic year for a sample of 23 private colleges in California was
$38,500 with a standard deviation of $7700. A dotplot shows that it
is reasonable to assume that the population is approximately
normal. Can you conclude that the mean tuition and fees for private
institutions in California is greater than $35,000? Use the α=0.05
level of significance and the P-value method with the TI-84 Plus
calculator.

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.

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.

In the academic year 2014–15, it was found that the national
average for one year of tuition and fees at a private institution
of higher learning was $24481 with a standard deviation of $1492.
The current estimate for the 33 institutions of higher learning in
Louisiana indicates an average of $19,785 per year. Answer the
following and determine whether this is a significantly lower
expected cost.
Step 1 of 5: What type of hypothesis test should be performed
here?
Step...

A sample of 37 observations is selected from a normal
population. The sample mean is 25, and the population standard
deviation is 5. Conduct the following test of hypothesis using the
.05 significance level. H0 : μ ≤ 24 H1 : μ > 24 (a) Is this a
one- or two-tailed test? "One-tailed"-the alternate hypothesis is
greater than direction. "Two-tailed"-the alternate hypothesis is
different from direction. (b) What is the decision rule? (Round
your answer to 2 decimal places.) H0,when...
