Over the past 20 years the 12 members of the Organisation of Petroleum Exporting Countries have made repeated attempts to restrict output in order to maintain high crude oil prices. Between 1990 and 1995, however, crude oil prices dropped by about 20%, due in part to increased production from the former Soviet Union, Latin America, Asia and the North Sea. In light of these increases in oil production from non-OPEC countries, what must OPEC do to maintain the price of oil at its desired level? Do you think this is easy for OPEC to do? Explain that in not less than 500 words.

Septimus was the seventh born child in his family; that is why he was called Septimus - which comes from the Latin word for 'seventh.' Despite the fact he had a numerical name, Septimus hated Hip Hop artists because so many of them appeared to be named after numbers (eg 50 Cent).
Because of his love of classical music, Septimus worked in the record indust1y as a company director for a recording company, My Masters Voice Ltd (or MMV Ltd). MMV Ltd specialized in recording classical music with a twist ( eg electric violin artists).
October 2013 proved to be a newsworthy month for Septimus and MMV. First, Septimus received a confidential report that MMV was going to merge with the leading recording company on earth, Mowertown. On hearing that news, Septimus purchased further shares in MMV and Mower-town. He purchased these shares in his own name. Secondly, at a Halloween party, one of the artists who records with MMV said to Septimus: "I'm really happy, the motor company my dad works for - Four Wheels are Better than None Ltd - is about to be cleared by a government enquiry - it turns out their quad-bike wasn't designed badly, after all. But please do not tell anyone I told you." Septimus subsequently bought shares in Four Wheels are Better than None. Finally, Septimus read an article in the No Idea Magazine that said smart investors were now buying shares in garden supply companies. Septimus went out and bought gardening shares.
(a) ASIC is now investigating Septimus' share purchases. They seek your advice on whether his three purchases have breached the Corporations Act. Advise ASIC giving legal reasons.
(b) One work experience cadet at ASIC learns about the Septimus matter and says: "The law relating to this matter is confusing. I am not sure whether Septimus' share purchases are governed by directors' duties or some other part of the Corporations Act. Also, even if he pleads guilty, I cannot make any sense out of the principles courts apply when sentencing offenders. I think the law is soft on white collar crime." Do you agree? Discuss this statement and in so doing, explain the relevant (white collar crime) sentencing principles to the cadet. Are you aware of other problems ASIC has had in white collar crime law suits? If so, discuss them.
(c) Imagine the above facts slightly change. First, instead of buying shares in Mower-town in his own name, Septimus instructs his accountant to buy the shares using a family company. Might that change the sections under which ASIC prosecutes Septimus? Why?
(d) Finally, imagine the facts change again. This time, instead of buying shares, Septimus makes a statement to the stock exchange which he knows is incorrect. When ASIC read the minutes of one directors' meeting, they find evidence that Septimus must have known the true situation. When confronted with this evidence by ASIC, Septimus simply says: "Well, the minute taker must have got it wrong." What are Septimus' prospects of success?

Complete PigLatin program in Windows Forms GUI. Zip the solution project file and attach to this submission. Do this in the GUI format (Windows Form). Be sure and add a Clear Button to reset for entering another word or words.
PigLatinGUI
Basic Steps in Creating your Program
Your program assignment
Pig Latin is a nonsense language. To create a word in pig Latin, you remove the first letter and then add the first letter and “ay” at the end of the ford. For example, “dog” becomes “ogday” and “cat” becomes “atcay”. Write a program named PigLatin that allows the user to enter a word and display’s the pig Latin version.
For words which begin with vowel sounds or silent letter, one just adds "yay" to the end. Examples are:
Another less common way some speakers may use a different ending for words starting with vowels is adding "way" (or "wa") to the end. Examples are:
You could use the split command to enter more than one word. Indicating delimiters
char[] delimiterChars = { ' ', ',', '.', ':', ';', '\t' };
string[] words = text.Split(delimiterChars);

For the following questions, identify the type of test that should be used. Simply use the corresponding letter: A) One-sample z test (for a mean); B) One-sample t-test; C) One-sample z-test for a proportion (or a chi-squared goodness-of-fit); D) Chi-square goodness of fit (and a z-test is not appropriate); E) Two-sample z-test for a difference between proportions (or a chi-squared test for independence); F) Chi-square test for independence (and a z-test is not appropriate); G) Simple regression; H) Multiple regression; I) Two-independent samples t-test (with homogeneity of variance); J) Two-independent samples t-test (without homogeneity of variance); K) Two-related samples t-test; L) One-way (independent measures) ANOVA; M) One-way Repeated measures ANOVA; N) Two-way ANOVA (independent, mixed, or repeated measures); O) Mann-Whitney; P) Wilcoxon; Q) Kruskal-Wallis; R) Friedman; If you are going down the interval/ratio branch, it is safe to use parametric measures, unless something is directly stated that clearly indicates otherwise, or unless the data strongly and unambiguously indicates otherwise. Similarly, it is safe to assume homogeneity of variance unless it is clearly indicated otherwise. Do not try to analyze whether or not the experiment is tenable or practical or flawless. This is not your concern right now. Almost all of the below were written by students in this class.
