1)INTRODUCTION: Colleges often report a combined tuition and fees figure. According to the College Board, the average cost of tuition for the 2017–2018 school year was $34,740 at private colleges, $9,970 for state residents at public colleges, and$25,620 for out-of-state residents attending public universities. Assume average yearly tuition cost of instate residents of 4-yr. public college is (mu) “μ” >/= is $12070 per year. (Null Hypothesis))

• Research online (by going to at least 15 college websites) to find costs of different public colleges to test this claim. (Hint: use Facts & Figures e,g Rutgers University,NJ)
• Use the T-test for a mean, since your sample is going to be less than 30 and an unknown population standard deviation.

Note: Make sure that your numbers only contain undergraduates and not graduates. As some of the websites were specific as to undergraduate or graduate and some probably contain both.

HYPOTHESIS: I think the average cost of tuition is lower than the assumed average stated.

Ho: μ (mu) >/= $12070.

H1: μ (mu) < $12070 (Claim)

DATA COLLECTION: Collect undergraduate students enrollment data from various college websites. Tabulate cost of tuition per year and the number of students enrolled. I already collected data for #1,an example and tubulated it as follows:

#	College	Tuition(In-state)	Number of Students
1	Rutgers University–New Brunswick	$11,999	49,577

• Find the lowest and the highest tuition. Calculate Range, Mean and Median for tuitions fees and enrollments.

HYPOTHESIS TESTING : (T-Test for the Population Mean, When σ Is Unknown(T-Test for a Mean)

Step 1: Identify the null and alternative hypotheses

Step 2: Set a value for the significance level, α = 0.05 is specified for this test

Step 3 : Determine the appropriate critical value

(Hint: Find the critical value at a=.025 and d.f. = 14, the critical value is –2.145.)– one tail

Step 4: Calculate the appropriate test statistic (i.e t-test statistic-“t alpha” )

Step 5:Compare the t-test statistic with the critical t-score.Compute the sample test value.

Step 6: Make the decision to reject or not reject the null hypothesis.

Step 7: Summarize the results. (conclusion)

2)Chi-Squared Independence Test

• Step 1: State the hypotheses and identify the claim. E.g. I claim that there is a correlation between the number of students at a college and the cost of tuition per year. Here is the data that is collected: (just an example to show the table – can change figuresif needed) Suppose α = 0.05 is chosen for this test

Cost of Tuition			Number of Students
	1000-9999	10000 -19999	20000 -29999	30000 – 39999	40000 – 49999	Total
$3000 – $6000
$6001 -$9000
$9001 – $12000
$12001 – $15000					1
$15001 -$18000
Total

Ho: The cost of tuition is independent of the number of students that attend the college. (x²=0)

H1: The cost of tuition is dependent on the number of students that attend the college. (claim : x²>0)

Step 2: Find the critical value

Step 3: Compute the test value. First find the expected value:

Step 4: Calculate the chi-square test statistic,

Step 5: Make the decision to reject or not to reject the null hypothesis.

Step 6: Summarize the results.

Anova Question (two-way ANOVA -with replication)

3)The following table show the standardized math exam scores for a random sample of students for three states. The sample included an equal number of eight-graders and fourth-graders.

	Tennessee	Florida	Arizona
Eight Grade	260	292	286
	255	260	274
	247	287	290
	277	280	269
	253	275	284
	260	260	297
Fourth Grade	275	270	286
	248	283	290
	250	280	295
	221	270	278
	236	283	258
	240	290	287

• Perform two-way ANOVA (with replication) using α = 0.05 by defining Factor A as the state and Factor B as to whether the student was an eighth-grader or a fourth-grader.
• Test the effects that the state and the grade of the student have on the standardized math score
• State sources of variation within sample .

Cultural Training

Imagine that your organization has asked you to move to another country and perform a job that is critical to the success of the organization. Note: You will be given the opportunity to take your family with you on this assignment.

For this discussion forum,

1. Select a country where you could perform a foreign work assignment.
2. Explain and discuss why it is critical for employees (and their families) to have cultural training before embarking on an overseas assignment.
3. Also discuss the specific cultural training you (and your family) would need in order to work in the country you chose to write about. What risks would their be to your family and to your organization if this training was not provided by the organization.

Note: This is for a discussion forum. 75-150 words are required.

Understanding the responsibility and concerns of healthcare is important
in creating policies that leadership can use to streamline success. If
strategic leadership is not realized over time,  healthcare
organizations’ political influences may face challenges and create
public disinterestedness in health policies.  These issues create
restrictions  on the healthcare organization’s ability to meet its
financial budget, gain community’s trust and involvement, and secure 
political influence(s). This negatively impacts the overall performance
of the healthcare organization. The ideas of process innovation, risk
taking, health building analysis, and governance greatly impacts
“sense-making” for those being led. These ideas bring understanding to
the role of governance in the organization. Review the case study
“Australian Surgery Indicator Makes the Front Page” in Chapter 15 of
your textbook and discuss the following questions in a minimum of 250
words:

• After your review, do the conclusions you draw from the case justify the headline? Why or why not?   
• Discuss the indications found in Table 15-1 and their effect on the health care organizations efficiency in elective surgery.
• Evaluate the avoidable rate of canceled surgeries and develop an implementation plan to overcome the concerns.
• Develop a mini policy to address the issues between the doctors and the organization.

Assignment is attached below in the file I uploaded. Part 3 you will be unable to do and I will do myself. Also if you are able to pull up t he lecture for correlations, regression etc. Please let me know and I will attach them.

Review the first part of these lectures describing statistical tests
for which types of variables to analyze (you do not need to know yet how
to run your variables in SPSS – that’s in Weeks 4 and 5!).

For this class, you may be able to use an ordinal variable in place
of a numeric (interval/ratio) variable when the ordinal variable makes
numeric sense (for example: 1 = low, 10 = high).

Correlations Correlations
(I would probably recommend regression over correlations for your MAIN
method of analysis, but there may be times when correlations are
appropriate)
