Please create a C++ program that will ask a high school group that is made of 5 to 17 students to sell candies for a fund raiser. There are small boxes that sell for $7 and large ones that sell for $13. The cost for each box is $4 (small box) and $6 (large box). Please ask the instructor how many students ended up participating in the sales drive (must be between 5 and 17). The instructor must input each student’s First name that sold items and enter the number of each box sold each (small or large). Calculate the total profit for each student and at the end of the program, print how many students participated and the total boxes sold for each (small and large) and finally generate how much profit the group made.

E 5-2B. Stage One ABC at a College: Assigning Costs to Activities An economics professor at Prince Town University devotes 60% of her time to teaching, 35% of her time to research and writing, and 5% of her time to service activities such as committee work and student advising. The professor teaches two semesters per year. During each semester, she teaches one section of an introductory economics course (with a maximum enrollment of 50 students) and section of a graduate economics course (with a maximum enrollment of 30 students). Including course preparation, classroom instruction, and appointments with students, each course requires and equal amount of time. The economics professor is paid $250,000 per year. Required Determine the activity cost of instruction per student in both the introductory and the graduate economics courses.

The Graduate Record Examination (GRE) is a test required for admission to many U.S. graduate schools. Students' scores on the quantitative portion of the GRE follow a normal distribution with mean 150 and standard deviation of 8.8. In addition to other qualifications, a score of at least 160 is required for admission to a particular graduate school.

a. What proportion of combined scores can be expected to be over 160?

b. What proportion of combined GRE scores can be expected to be between 155 and 160?

c. What is the probability that a randomly selected student will score less than 150 points?

d. Historically, Department of History at NYU has admitted students whose quantitative GRE score is at least at the 61st percentile. What is the lowest GRE score of the students they admit?

e. Determine the range of scores that make up the middle 95% of the scores.

Micromedia offers computer training seminars on a variety of topics. In the seminars each student works at a personal computer, practicing the particular activity that the instructor is presenting. Micromedia is currently planning a two-day seminar on the use of Microsoft Excel in statistical analysis. The projected fee for the seminar is $600 per student. The cost for the conference room, instructor compensation, lab assistants, and promotion is $9600. Micromedia rents computers for its seminars at a cost of $60 per computer per day.

a) Develop a model for the total cost to put on the seminar. Let ? represent the number of students who enroll in the seminar.

b) Develop a model for the total profit if ? students enroll in the seminar.

c) Micromedia has forecasted an enrollment of 30 students for the seminar. How much profit will be earned if its forecast is accurate?

d) Compute the breakeven point.

Consider the following schema:
Student(id, name)
Registration(id, code)
Course(code, instructor)

A) Explain how we can violate the foreign key constraint from the id attribute of Registration to the Student relation.

"DRESS CODE"

I NEED YOUR OPINION ABOUT THIS SITUATION, PLEASE WRITE A PARAGRAPH IN THE FORM OF FORMAL ESSAY. THANKS.

THIS IS ABOUT GRADUATE SCHOOL NOT UNDERGRADUATE

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The school has a dress code policy. Students start to be absent and the absent rate increased, thus school changed policy and let the students wear casual attire for 1 day a week, in this case; the absent rate dropped. School decided to change the policy for Art students and let them wear casual attire for 3 days a week, so the school realized the absent rate incredibly decreased.

What is your opinion about this situation? Please write a paragraph in form of "Formal Essay".

(Please note that the school has Dress Code policy and wants to know that you will be a good fit in this school)

Thanks!

This essay is general in nature and is aimed at assessing the students’ understanding of key concepts related to strategic planning and management, focusing on the importance of the process of designing vision, mission and value statement for an organization, the role of objective setting (long-term objectives and their organizational benefits) in the process as well as the stages of developing strategic plans, focusing mostly on strategy formulation and implementation.
On the theoretical level, students are expected to express their agreement or disagreement with the views in the literature based on their professional experience. On a more practical level. using the ‘Comprehensive Strategic-Management model (David 2013, students are encouraged to interpret the stages through examples from their own organizations. The essay should conclude with an original summary of the theoretical discussion, highlighting the key lessons learned from theory in light examples presented.

Confidence Interval and Sampling Error:

You decide to conduct a poll of students in order to determine the percentage of students (p) who agree with the statement “Hot dogs are one of my

favorite foods”. In your poll, you find that 85 out of 100 students agree.

a)

Compute a 95% confidence interval for p.

b)

You wish to ensure that the margin of error is no larger than 2.5%. How many students should you include in your next poll?

Suppose that you are the manager of a casino and you collect data on one of your roulette tables. You find that among the last 10,000 bets, there were only 350 bets for which a red or black number did not win. On average, you expect the proportion of winning bets for black or red to equal p=18/19.

a) Compute a 95% confidence interval for the proportion of winning black or red bets.

b) Conduct a two-sided hypothesis test (α=0.05) for HO: p=18/19. State the relevant p-value and your decision whether to reject or not reject HO.

c) Compare your results in part (a) and (b). Are they consistent?
