As part of a course project, a statistics student surveyed random samples of 50 student athletes and 50 student non-athletes at his university, with the goal of comparing the heights of the two groups. His summary statistics are displayed in the provided table.

a). Which data analysis method is more appropriate in this situation: paired data difference in means or difference in means with two separate groups? Explain briefly.

b). Construct a 99% confidence interval for the difference in mean heights between student athletes and non-athletes at this university. Use two decimal places in your margin of error.

c). Test, at the 5% level, if student athletes at this university are significantly taller, on average, than student non-athletes. Include all of the details.

11. (20) GPA distribution in UPW university is a normal distribution with an average of 2.68 and a standard deviation of 0.4.

(a) About what proportion of the students have GPA at most 3?

(b) About what proportion of the students’ GPA are between 2 and 3?

(c) The President of the university is establishing a new scholarship, the minimum qualification is that students GPA have to be among top 3%, what is the numerical GPA a student must have in order to qualify?

(d) A students’ club has a minimum GPA requirement of 2.7 or higher. You heard that Kelly is going to attend a club members’ meeting, you are wondering: what is the chance that Kelly’s GPA is lower than 3.3?

(e) If we randomly choose 7 students in the university, what is the chance that at least 2 have GPA over 3.3?

Assume that the mean SAT score of students admitted to Northeastern Illinois University is 1090. The members of the Psychology Department believe that students who decide to major in Psychology have higherSAT scores than the general population of students at the university. A sample of N= 10 newly declared Psychology majors consent to have their entrance records reviewed.

Their scores are as follows: 1276, 1248, 1066, 1106, 1138, 1215, 1168, 1185, 933, and 1425.Can the department conclude that Psychology majors have higher SAT scores than the university as a whole?

For this assignment, you will be creating a Dorm and Meal Plan Calculator.

A university has the following dormitories: Allen Hall $1,500 per semester Pike Hall $1,600 per semester Farthing Hall $1,800 per semester University Suites $2,500 per semester The university also offers the following meal plans: 7 meals per week $ 600 per semester 14 meals per week $1,200 per semester Unlimited meals $1,700 per semester Create a multi-form Windows Forms Application with two forms.

The main form should allow the user to select a dormitory and a meal plan. The application should show the total charges on the second form.

Create a recommendation for a new client wishing to adopt a retirement plan, providing support for why you believe this is perhaps the best plan.

The new client is a US-based subsidiary of a German pharmaceutical firm. It began hiring US-based employees less than a year ago and currently has about 35 hired. The firm is finding it challenging to compete with larger companies here in the US without offering benefits similar to those larger firms such as retirement plans. The CFO of the firm has come to you and is giving you the following fact set in addition to the above:

• Anticipate hiring another 70 employees in the next 24 months,
• they would like a very high degree of latitude with respect to company contributions,
• they are willing to make a commitment to low-level contributions at this time however only for those employees who are contributing themselves,
• currently half of their workforce, and within 24 months still about one third of their workforce is anticipated to make more than $130,000 a year in compensation

A wonderful, smart student named “SHINY STAR” enrolled in an online college, called “SUBPERB 4-YEAR TURN YOUR LIFE INTO A MILLION DOLLARS UNIVERSITY.”

When Shiny Star was meeting with his advisor, the advisor told Shiny Star that the college was one of the cheapest colleges around.

However, 2 years into his degree, Shiny Star compared prices and realized that other colleges around were much, much cheaper than “SUBPERB 4-YEAR TURN YOUR LIFE INTO A MILLION DOLLARS UNIVERSITY.”

Shiny Star was upset. He sued the school in District Court, claiming the school had violated competition laws and false advertising laws.

In defense, the University argued that its’ enrollment agreement clearly contained a requirement that all disputes be arbitrated. Shiny Star signed this agreement when he paid and enrolled in classes. The University presented the signed agreement to arbitrate and the District Court dismissed Shiny Star’s case.

This is an example of a contract that agrees to the place or the manner in which the lawsuit will be handled.

What is the legal term for such an agreement to handle the case through arbitration, for example?

Economics Hypothetical Scenarios: Please Answer both of them thank you

1.a) Think about two people: a poor person and a rich person. Let each person have the
same nicotine habit (i.e. they consume cigarettes at the same rate) and suppose the
government imposes a tax on cigarettes to pay for health care, who is hurt more by
the tax? Why?

b)Assume that I have a doughnut, and you have a doughnut, and there is one doughnut
lying on the ground.
i) Is this efficient?
ii) If I just take the doughnut from the ground and cram it down my throat without
sharing it with you, is that efficient?
iii) If we fight over it, and smoosh half of it in the fight, is that effcient?

iv) if one of us agree to split half of it in the fight, is that efficient?
v) If a third party offers to split the doughnut fairly between us in exchange for a quarter of the doughnut is that efficient?

vi) If a third party forces us to split the doughnut fairly between us in exchange for a quarter of the doughnut is that efficient?
