An experiment is conducted to determine if classes offered in an online format are as effective as classes offered in a traditional classroom setting. Students were randomly assigned to one of the two teaching methods. Data below.

a. Test the claim that the standard deviations for the two groups are equal. What is the p-value of the test?

b. Construct a 95% confidence interval on the difference in expected final exam scores between the two groups. Does the data support the claim that there is no difference?

Data obtained from the National Center for Health Statistics show that men between the ages of 20 and 29 have a mean height of 69.3 inches, with a standard deviation of 2.9 inches. A baseball analyst wonders whether the standard deviation of heights of major-league baseball players is less than 2.9 inches. The heights (in inches) of 20 randomly selected players are given below.

Use Minitab Express to test the analyst's hypothesis at the α = 0.10 level of significance. Report your answers to three decimal places, where applicable.

With a P-value of , we  (reject / fail to reject) the null hypothesis.  
The given data  (does / does not) provide significant evidence that the standard deviation of heights of baseball players is  (more than / less than / different from) 2.9 inches.

As a financial analyst you have been asked to analyse an ASX listed company. The company is one of your choosing. Your task is to make a recommendation as to whether this company is an attractive investment opportunity. Before you draw a conclusion, you are required to: 1) Discuss how successful the company has been at maximizing stakeholders value over a set analysis period. This period may be 12 months, 2 years, or 5 years. 2) Analyse the company's share price history and traded volumes over the chosen analysis period. 3) Calculate the return for investing in the company both short term and long term and identify the main causes of its volatility in return over the corresponding holding period. The discussion of volatility should consider economic-wide and firm-specific factors. 4) Apply the valuation technique(s) taught in this course and undertake a current valuation of the equity for your company. Based on your calculation, would you recommend a prospective investor to buy, hold or sell this security and why? 5) Analyse the company's dividend policy. Should the company follow a progressive dividend policy? Critically evaluate factors that are affecting corporate dividend policy and how your company's dividend policy may have influenced its capital structure and share price. 6) Analyse the company's capital structure. How would you describe the current capital structure for your company and justify with reasons that should potential investors view this company as a favourable investment choice? Based on the attempt to all of above questions conclude whether your company is an attractive investment opportunity. You should clearly explain your assumptions used in the valuations and estimations and critical discuss the limitations of your analysis and any other risks that may affect investors' decision making.

Suppose that many stocks are traded in the market and that it is possible to borrow at the risk-free rate, r_ƒ. The characteristics of two of the stocks are as follows:

a. Calculate the expected rate of return on this risk-free portfolio? (Hint: Can a particular stock portfolio be substituted for the risk-free asset?) (Round your answer to 2 decimal places.)

Oil is an example of a commodity, which is something of value that is traded in bulk in global markets. Other examples are gold, coal, natural gas, grain, etc. Commodity prices are the result of buyers and sellers interacting in highly competitive and dynamic markets. The article below shows trends in recent history for the price and quantity of oil being traded in the world markets. Each dot represents an equilibrium at a point in time. What are some factors that affect the demand and supply of oil? How would changes in demand and supply get us from one equilibrium to the next? https://www.nytimes.com/interactive/2015/09/30/business/how-the-us-and-opec-drive-oil-prices.html (Links to an external site.)Links to an external site.
