I need some assistance with the following

From my textbook page 193194 International Business competing in the local market 13th edition by Charles W.L. Hill regarding the Closing Case Trade Wars Article - {see below] what economic theory of trade do Donald Trump's views seem most closely aligned with? At 3:50 am. on March 2, 2010, Donald Trump, the 45th President of the United States, took to his favorite medium, Twitter, to espouse his views on an important policy issue: international trade. He tweeted \"When a country [USA] is losing many billions of dollars on trade with virtually every country it does business with, trade wars are good and easy to win. When we are down $100 billion with a certain country and they get cute, don't trade anymore we win big. It's easy!"*Trump's tweet was a response to backlash over his decision to impose a 25 percent tariff on imports of steel, and a 10 percent tariff on imports of aluminum. The Trump administration claimed these tariffs were necessary to protect two industries that were important for national security. His critics had a different take. They argued that the tariffs would raise input costs for con-sumers of steel and aluminum, which included construction companies, manufacturers of construction equipment, appliance makers, auto manufacturers, makers of containers and packaging {e.g., beer cans], and aerospace companies. Among those hit by higher costs due to these tariffs would be two of the U.S.'s largest exporters: Boeing and Caterpillar Tractor. The critics also noted that there are only 140,000 people employed in the steel and aluminum industries, whereas 6.5 million Americans are employed in industries that use steel and aluminum, where input prices have just gone up. 4. [4 Marks] Consider the perfectly competitive timber industry. It is initially in long run equilibrium at quantity Qo and price Po a) Draw a supply and demand diagram for the timber market showing this equilibrium. by Draw a diagram for a typical logging firm in its initial long run equilibrium, showing it's Marginal Cost, Average Total Cost, and Long Run Average Cost curves, Are any profits being made by this firm? c) A major use for timber is the creation of paper products. Suppose that a ban on disposable plastic shopping bags substantially increases demand for paper bags. What happens to your diagram in part (a)? Use your diagram from part (b) to show how the firm reacts to this new situation. Are any profits being made by this firm? d) Explain how this industry adjusts to its new long run equilibrium using both the diagrams from parts (a) and (b) (You may assume that it is a constant cost industry)Question 4 Andre Strauss and his orchestra are well known musicians who bring an element of fun into the enjoyment of music. They are famous throughout the world their Waltz music. Three Quarter Time Ltd. is considering sponsoring a concert in London to promote the Waltz and increase their sales in the process. The cost of the sponsorship will be 0.5 million. The concert is scheduled to be held in Spring 2013 in a reputable venue. Three Quarter Time Led has approached your company for a loan for these funds. Assuming that the Balance Sheet would continue to remain the same as the current published accounts for the year ended 31 August 2012, till Spring 2013, until the proposed loan is granted, calculate the gearing of the company and comment on this and all other findings particularly on the qualifications of the audit report. (20 marks)Question 5 The company has made a profit of E13,587 in the year 31" August 2012, yet has generated a operating cash OUTFLOW of E109,690. a) Explain, using both facts and figures, how Three Quarter Time Ltd has made a profit yet has suffered a significant negative operating cashflow. (10 marks) b) Evaluate the significance of the cashflow statement when making credit decisions. (6 marks) c) If the adjustment outlined in the auditor's opinion was put in place what effect would this have on the Profit and Loss Account and on the Cashflow Statement. (ignore any tax effect).

A simple random sample of 64 students is taken. a. What are the expected value, standard deviation, and shape of the sampling distribution of the sample mean? b. What is the probability that these 64 students will spend a combined total of more than $715.21? C. What is the probability that these 64 students will spend a combined total between $703.59 and $728.45? 26. It is crucial that the variance of a production process be less than or equal to 25. A sample of 22 is taken. The sample variance equaled 26. a. Construct a 90% confidence interval for the population variance. b. Construct a 90% confidence interval for the population standard deviation. C. State the null and alternative hypotheses to be tested. P Compute the test statistic. e. The null hypothesis is to be tested at the 10% level of significance. Using the critical value approach, state the decision rule for the test. f . What do you conclude about the population variance? 27. Below you are given a partial computer output based on a sample of 25 observations relating the hourly wage (Y), number of years of schooling (X,) and score on an aptitude test (X2).
