To determine the number of trout in a lake, a conservationist catches 125 trout , tags them, and releases them. Later 112 trout are caught, and it is found that 62 of them are taged. Estimate how many trout there are in the lake ?

Indian passport. Amandeep works with the New Zealand Princess Cruises tours and most of the
income year is in New Zealand. He signed an employment contract for this position in the company’s
Australian office in Sydney. Amandeep has two kids that are living with his wife Sandeep in Sydney.
Three years ago, Amandeep purchased a unit apartment in Sydney. Amandeep and his wife holding
dividend yielding shares in an Indian public company called Hindustan Unilever. Amandeep and
Sandeep have an Australian bank account as well. Amandeep’s employer pays his salary to this bank
account every fortnight.

tours and he is using this package with his family traveling in Australia interstates or moves to India to
visit his in laws.
Required:
With reference to the relevant laws, discuss whether Amandeep is an Australian resident for tax
purposes and also critically discuss whether Amandeep needs to pay income tax on his salary and
investment income explained above. (10 marks, maximum 400 words)

A new type of light bulb has an average lifespan of 1200 hours with a standard deviation of 75 hours. Use the table to find the probability that a light bulb chosen at random will last less than 1170 hours.
How do I find probability using a table? What is the formula?

The econometric analysis
Each topic contains one or more research questions, and as a group you have a large degree of freedom on how you answer these research questions. You have choice over which variables are to be in the right hand side of models, which estimator and standard errors to use, and how to structure your arguments. However, you must explain where you began and how you arrived at your preferred model or models. This might include devising a simple theoretical economic model with equations that guide the econometric analysis.
Some general notes you may want to consider:
1. Should the variables enter the specification in levels or logs? Should you add squares? Should there be any interaction terms?
2. Think about all that you have learnt in this course and past econometrics/statistics courses, and how the techniques may help you answer the research question(s).
3. When undertaking the project run multiple models that you believe are decent candidates, and then compare the results.
4. When specifying the model, the goal is to add as much information as possible whilst keeping the model parsimonious.
5. You are not expected to use any estimator that has not been covered in ECON3208/5208. Do not use any method that you do not understand or can’t explain/interpret.
6. Whatever econometric model you use, you must state the assumptions behind the model, and whether you believe they apply in the case you have.
Writing up your analysis
The project must be between 9 to 12 pages. You should use 12 pt fonts and normal margins. In tables, it is acceptable to use smaller fonts but you should not use anything smaller than 10 pts. You should read Chapter 19 of Wooldridge to get insights about how to proceed with an empirical project.
As a guide, you could think of including the following sections (this is merely an example of how to structure the project, you may deviate from it):
1. Introduction (1 page): Discuss previous literature (refer to one or two papers, and broadly describe their main results) and any policy issues and implications.
2. Data (1 page) Describe the variables you chose to include in the model, the number of observations, and justify any decisions you made in selecting the variables. Include basic descriptive statistics.
3. Model (2 pages): You can describe briefly a theoretical model in order to motivate your choice of variables and to help with the interpretation of the results. The model has to be developed on the grounds of the properties of the dependent variable and the available regressors. Then describe the econometric model(s) in some detail. This can also be done in the results section.
4. Results and interpretation (3 pages): This is likely to be the main section in your paper. Describe your econometric models and your results. Interpret the results. Discuss likely problems with the model and possible violations of your main assumptions. Try to say something about the effects of possible biases on your findings. This should also include a careful account of relevant hypothesis tests and their meaning.
5. Diagnostics and Sensitivity analysis (2 pages): This is also a crucial part of your paper. You want to convince the reader that your results are real and not just an artifice of the particular model you are using. Run different models, change some of the decisions you made in manipulating the data and rerun the models. Describe your results and say if they remain true with these changes or if they are sensitive to the exact model/data assumptions you are making. Modelling of real life data is always difficult. It is therefore important that you are able to look critically at your results and are able to identify drawbacks and shortcomings of your findings.
6. Conclusions (0.5 pages): Restate your main results and say how you would expand the paper if you had more time, more data, etc….
7. References (0.5 pages): Reference your textbooks (if you used them) and any article you have read and used as a basis for your discussions and decisions.
The scenario for this assessment is a hypothetical future system that helps governments to manage
traffic flow in municipal localities. You should imagine that the local Road Traffic Authority has put
out a Request for Proposals (RFP) for appropriately qualified consultants to undertake a body of
work that would help to scope the data requirements for such a system. With your success in your
Torrens University Australia degree so far, and other similar projects that have garnered you some
sustained success in the eyes of the profession and community, you have been shortlisted among no
less than 10 other consultancies. There are expectations from them, then, as to the standard of
report you will produce.
While there has been a tremendous amount of attention given in the media and in scientific circles
to the progression and uptake of autonomous vehicles, their widespread adoption has not yet
proliferated: there are reasons for this that you will need to take into account in your deliverable.
The local Road Traffic Authority is, with several other bodies, lobbying the government on what it
can manage in the emergent world of technological change and the capability of artificial
intelligence. An alternative model has been proposed that the Road Traffic Authority believes to be

preferable to autonomous vehicles and it involves a system that would control all non-autonomous,
driverless vehicles through a traffic management and routing system.

You are to develop a MATLAB function that outputs the trigonometric Fourier series of the input function. Hint You may use your test signal and the hand calculations to verify your solution. The function must take the following inputs:
• Any periodic function over a single period as s_hinf. This signal will be in the form of a discretely sampled array (similar to Problem 3): • The time vector that the periodic noise signal was evaluated over as t; and • The number of harmonics that the Fourier series will be evaluated as N.
The function must output:
• The trigonometric coefficients of the input periodic function as a0, an and bn; and • The trigonometric Fourier series approximation of the input periodic function evaluated with N harmonics, saved as s_approx.
The variable an and bn must be stored as a row vector where an = b,, = lb b2, bN: The trigonometric coefficients must be computed numerically using MATLAB. It is expected that any integrals will be found numerically using a Riemann sum, i.e. do not use the trapz or syms functions. Please note. this function is not related to the signals given in Problems 1 and 2.
Aniline is being removed from water by solvent extraction using toluene. Aqueous and organic phases will form after adding the organic solvent into the water phase. The extraction is carried out in a 10-stage countercurrent tower, shown in the following figure. The equilibrium relationship valid at each stage is, to a first approximation:
