St. Gallen American School is an international private elementary school. In addition to regular classes, after-school care is provided between 3:00 pm and 6:00 pm at CHF 10 per child per hour. Financial results for the after-school care for a representative month are as follows:

The director of St. Gallen American School is considering discontinuing the after-school care services because it is not fair to the other students to subsidize the after-school program. He thinks that eliminating the program will free up CHF 1,300 a month to support regular classes.

1. Compute the financial impact on St. Gallen American School from discontinuing the after-school care program.
2. List three qualitative factors that would influence your decision

Essay: 2 [ x - (4 + 2x) + 3 ] - 2x - 2 = 4 [2x - (3 - x) + 5] + 6x + 28

Students, you have to do an essay for this discussion. The essay is consist of a introduction, a body, and a conclusion. You have write this essay like you are teaching your children, co-worker, or a stranger how to work this problem. The introduction is where you will define all of the terms of the problem and list all the rules. In which, you tell me what type of problem it is, if it's an equation and linear, if it has parenthesis and bracket, which have to be defined and what you would to solve the problem. The body is where you will work the problem, write out in sentence structure how you work the problem. Make sure you put the problem in your essay and everything that you did to work the problem. Lastly, the conclusion is where you will explain what the person should get for working the way that you worked it, and what they should learn

8. (6) Researchers believe that human male infertility has increased significantly in recent years due to exposure to BPA and related chemicals. A recent study provided evidence for this by interviewing lab technicians at a sperm donor bank in Chicago, which purchases sperm mainly from college students from a small local college. They report that the number of donors with acceptable sperm counts (at least 15 million sperm per milliliter of semen) has declined by almost 60% since 1980. Relate the following questions to this information:

1. Define sample vs. population and explain what each would be in this study.
   • Sample is one selection from a population. Sample would be
2. Define Random Variation and explain how it could be a factor in making conclusions about sperm quality and quantity?
3. Define confounding factor, and list one potential Confounding factor in using this sample to represent the population.
4. Provide an argument for why this sample might not contain independent data points.
5. Define sampling error and discuss whether it might be occurring in this study.

Exercise 5: Inappropriate Interview Questions Exercise: An interview question is not in itself illegal, but how the interviewer uses the answer can be. The goal of an interview is typically to obtain important information about the candidate while reinforcing the organization's employer brand and maintaining a positive employer image. It can be helpful to practice recognizing inappropriate interview questions and identifying ways to more appropriately get the information that you are looking for from the candidate. Working with a group of 2-3 students, read this list of interview questions and explain why each is inappropriate. Try to identify the type of information being requested that may be important for the position, and identify a way to obtain the same desired information in a more appropriate way.

The Four Corners Theater’s mission is to increase access to the arts for the community of Four Corners. The Theater group owns a debt-financed theater and puts on several plays throughout the year, as well as providing facilities for many other activities. Four Corner’s Theater is a well-established, not-for profit organization exempt under IRC Sec. 501(c)(3).

Identify whether the following activities would be subject to unrelated business income tax (UBIT) and explain why or why not.

1. Rental of the facility to the high school drama club.
2. Fees for summer acting classes for primary school students.
3. Sale of tickets to plays put on by the Four Corner’s Theater group.
4. Sale of season ticket membership list to a local book store.
5. Rental of two apartments in the facility.
6. Rental of meeting space to other local 501(c)(3) organizations for their monthly meetings.
7. Internet sales of gift shop items with the Four Corner’s Theater logo.

How do California high school students compare to students nationwide in their college readiness, as measured by their SAT scores? The national average scores for the class of 2017 were 533 on Evidence-Based Reading and Writing and 527 on the math portion.† Suppose that 100 California students from the class of 2017 were randomly selected and their SAT scores were recorded in the following table.

(a)

Do the data provide sufficient evidence to indicate that the average Evidence-Based Reading and Writing score for all California students in the class of 2017 differs from the national average? Use α = 0.05.

State the null and alternative hypotheses.

H₀: μ < 527 versus H_a: μ > 527

H₀: μ = 533 versus H_a: μ > 533     

H₀: μ = 533 versus H_a: μ ≠ 533

H₀: μ = 533 versus H_a: μ < 533

H₀: μ ≠ 527 versus H_a: μ = 527

Find the test statistic and the p-value. (Round your test statistic to two decimal places and your p-value to four decimal places.)

z=

p-value =

State your conclusion.

The p-value is less than alpha, so H₀ is rejected. There is sufficient evidence to indicate that the average Evidence-Based Reading and Writing score for all California students in the class of 2017 is different from the national average.

The p-value is greater than alpha, so H₀ is not rejected. There is sufficient evidence to indicate that the average Evidence-Based Reading and Writing score for all California students in the class of 2017 is different from the national average.    

The p-value is greater than alpha, so H₀ is not rejected. There is insufficient evidence to indicate that the average Evidence-Based Reading and Writing score for all California students in the class of 2017 is different from the national average.

Suppose that you win $2 for each black ball selected, you lose $1 for each white ball selected, and you get nothing for each orange ball selected. If the casino lets you play this new casino game with no entry fee, what is the probability that you will not lose any money? [7 marks]

Twenty-five percent of shipments come from factory 1 whose shipments contain 8% defective smartphones. Sixty-five percent of the shipments come from factory 2 whose shipments contain 6% defective smartphones. The remainder of the shipments comes from factory 3 whose shipments contain 4% smartphones. The company receives a shipment, but does not know the source. A random sample of 15 smartphones is inspected, and three of the smartphones are found to be defective. What is the probability that this shipment came from factory 2?
