Question

In the academic year of 2010-11, it was found that the
national average for one year of tuition and fees at a private
institution of higher learning was $24,897 with a standard
deviation of $1,347. 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 What type of hypothesis test should be performed here?

Step 2 State the null and alternative hypothesis.

Step 3 conclusion

Step 4 Choose your interpretation

Answer #1

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.

7) The average annual tuition and fees at all 4-year
institutions in the US in 2010 was $25,390 and in 2016 is estimated
to be $ 32,980. Let y be the average tuition and fees in the year
x, where x = 0 represents the year 2010. a) Write a linear equation
(point slope form), which would models the growth in average
tuition and fees at all 4-year institutions in the US in terms of
the year x. Plot the...

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.

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...

Suppose the national average for fees paid on a parking ticket
(not including any court involvement) is $24 with a standard
deviation of $6. Your local police department feels that they
charge less than this on average. Of the next 132 parking tickets
awarded, the average fee due is $23.
A)What type of hypothesis test should be performed here?
B)State the null hypothesis. and the alternative hypothesis.
C)State the p-value for your test.
D)Choose the appropriate conclusion for this test...

The National Average cost for a 4 year degree at a public
institution is roughly $39,500 for
students beginning in Fall 2016
22 students in a RCTC-Winona 2+2 are expecting an average cost
of $28,000 with standard
deviation of $2100
a) Setup a Hypothesis Test to answer “Do 2+2 Students pay the
National Average Price?”
b) Run your test at 99%. ( for 2-tail)
c) Explain your conclusion

During a given year, high school students earned a mean of
$1359. Assume that a sample consisting of 45 students at a school
was found to have earned a mean of $1382 with a standard deviation
of $210. Would a hypothesis test at the 0.01 significance level
suggest that the average earnings of this school were significantly
higher than the national mean? Formulate the alternative and null
hypotheses and do the necessary steps for hypothesis testing. Use
critical values to...

Question 1 (1 point)
Suppose the national average dollar amount for an automobile
insurance claim is $746.9. You work for an agency in Michigan and
you are interested in whether or not the state average is different
from the national average. Treating the national mean as the
historical value, What are the appropriate hypotheses for this
test?
Question 1 options:
1)
HO: μ ≤ 746.9
HA: μ > 746.9
2)
HO: μ > 746.9
HA: μ ≤ 746.9
3)
HO:...

Please answer both!!
Suppose the national average dollar amount for an
automobile insurance claim is $805.66. You work for an agency in
Michigan and you are interested in whether or not the state average
is less than the national average. The hypotheses for this scenario
are as follows: Null Hypothesis: μ ≥ 805.66, Alternative
Hypothesis: μ < 805.66. You take a random sample of claims and
calculate a p-value of 0.02 based on the data, what is the
appropriate conclusion?...
