QUESTION 17

A study finds that the proportion of high school students that use marijuana regularly is from 0.05 - 0.11. Confidence level - 95%. Which of the following statements is FALSE?

It is reasonable to say that more than 7% of high school students use marijuana regularly.

It is reasonable to say that no more than 10% of high school students use marijuana regularly.

The hypothesis that 7% of high school students use marijuana regularly cannot be rejected.

The hypothesis that 15% of high school students use marijuana regularly can be rejected.

1.Now state legislators want to make predictions about how changes in consumers’ budgets will impact their consumption behavior. If school supplies and salty snacks are both normal goods with school supplies on the x-axis of the graph and salty snacks on the y-axis, explain how a decrease in consumers’ budgets would impact the consumption of school supplies and salty snacks.

b)Can school supplies be an inferior good at all budget levels? What might the relationship between budget and consumption of school supplies look like?

4. A random sample of 860 births at St. Jude’s Hospital included 426 boys. The national proportion of newborn boy babies is 51.2%. Use a 0.01 significance level to test the claim that the proportion of newborn boy babies at this hospital is different than the national average.

a. Draw a normal curve for the sampling distribution for samples of size 860 births. Label the mean and the values for one, two and three standard deviations above and below the mean.

What is your view on this student's response from the example on school lunches? Please see below.

The example involves a public school cafeteria serving lunch. Some students pay full price for their food, but others receive lunch for a reduced price or for free under the federal National School Lunch Program. For simplicity's sake, let's assume the school cafeteria meets all nutritional requirements to qualify for NSLP - all it needs to do now is serve the lunches. The grant is expenditure driven - when the school district proves the reduced price and free meals have been provided, the federal government owes it a grant payment. (Again, we'll ignore the part of the program that involves school districts receiving free food products from the USDA to use in the meals.)

Student's Response: The school and student are conducting a nonexchange transaction when the school provides a lunch valued at X for free to the student. I base this on the GASB definitions of the two types of transactions. Exchange transactions are those in which each party receives and gives up essentially equal. Nonexchange transactions are those in which a government gives or receives value without directly receiving or giving equal value in exchange. The student receives a meal, so the school (government) provided value. However, the school did not directly receive any value from the student.

WG is one of the world’s leading makers of mobile phones, with market share of approximately 20%.Unlike any of its major competitors, it is based in Narnia, a high-cost, developed country. Narnia has very limited natural resources, but has developed significant expertise over the decades in high-end precision engineering and efficient use of materials. WG is quoted on the Narnian stock exchange, where it is the largest company by market capitalisation. It has a wide shareholder base including most Narnian institutional investors and private individuals. Its largest three shareholders are institutions who each own around 2% of the company.WG was founded in the 1960s to make telephone equipment and in the 1990s managers made a strategic decision to focus on the then-tiny mobile phone market. This was partly attributable to the Narnian government being among the first to fully deregulate their telecoms market, which lead to lower call costs. Narnia and its neighbouring countries are also fairly rural, and its populations were enthusiastic early adopters of mobile phones. WG was given a particular boost in 1995 when the transmission standard they had pioneered was adopted as the basis for calls by the government in Narnia and many other governments around the world. Serving a rapidly growing market, WG quickly gained economies of scale that allowed cheaper production than competitors emerging later. WG then exploited these to open up export markets all over the world,enhancing their advantage further. Unlike many of its competitors, who subcontract their manufacturing to others, WG assembles most of its own handsets. Its factories are mostly in Narnia, where it benefits from the highly educated population and the presence of high-quality local suppliers to carry out increasingly high-tech manufacturing processes. Narnia has very good communication links, which helps suppliers to deliver rapidly. Technology is advancing all the time and WG regularly launches new, more sophisticated devices, most recently a suite of smartphones. However, the fastest-growing demand is for cheaper, basic models which just carry out voice calls and text messaging. This demand is driven by users in developing countries, who are concerned to keep costs down, but also want the status of using a well-known brand such as WG. WG has invested significant resources in building up a local sales presence in these markets, which allows it to spot trends and produce phones tailored to local tastes and languages. Competition in the industry is intense, and has become more so due to a recent global economic downturn. The Narnian government has also announced new anti-pollution measures that will result in large-scale manufacturers having to pay more than previously to dispose of their waste products. Shortly afterwards, WG announced that they will increase the proportion of handsets manufactured in lower-cost countries from 15% to 40% over the next three years. Component manufacturers announced plans to follow them to the new locations. This will involve cutting over 1,000 jobs in Narnia. A spokesman for the Narnian government called the decision “disappointing”. A trade union official said, “WG has increasingly been putting pressure on its suppliers to lower costs and respond more quickly to market fluctuations. This has made it unprofitable for them to operate in Narnia and lead to decisions like this”. Required:

(a) Analyse WG’s environment using two appropriate models

(b) Discuss the main stakeholders in WG and how management could try to retain their support as it seeks to reduce costs.

Five years earlier, ABC school implemented a performance management system for all school employees. The performance management system was designed for teachers by the British Department for Education and Skills but was used to evaluate school support staff as well because there was no system specifically geared toward support staff. The school had no HR personnel to custom-design a system for support staff, and at the time, most of the emphasis in terms of performance management was paid to teachers. Because few support staff members were classified as exempt employees, a specialized performance management system was not perceived to be a priority.

Applying bench-marking on school, list the two approaches of Bench-marking, discuss how can it be applied to support School future performance

David is a high school senior. He must decide whether to work or go to college. If he has a high school degree, he will make $20,000 per year. If he has a college degree, he will make $35,000 per year. To get a college degree, he must go to school for one period at a tuition cost of $10,000. Assume David lives for 3 periods and his discount is 0.1. A. What is David’s direct cost of attending college? What is his opportunity cost? What will he decide to do?

B. Now, assume David can get a full-ride scholarship (thus H = 0). Now what will he do?

C. Since David is receiving a scholarship for his undergrad degree, he is now debating about going to grad school. If he decides to get his PhD, he must go to school in the first period (undergrad) at a cost of $0, and he must go to school in the second period (grad school) at a cost of $0. With a PhD, David can make $77,000 per year. Will David go to grad school? You only need to compare undergrad and grad school.
