| Question | Question 1 One of the most straightforward ways to quantify the biodiversity of an environment is simply to count the number of different species that can be found there, irrespective of how many times a particular species is observed. This measure is known as species richness. Write a function get_species_richness() that calculates the species richness of a habitat, based on a series of observations of various bird species. The function takes one argument: observed_list, a list of independent observations of bird species. The function should return a tuple consisting of: • the species richness, calculated as the number of different species observed; and • an alphabetically sorted list of the species that were observed. |

| Question | Problem Description – Forecasting Electricity Prices The problem is to forecast electricity price based on historical data. Let the temperature and total demand of electricity at time instant t be T(t) and D(t) respectively. The goal is to predict the recommended retail price (RRP) price by using some historical data as system inputs. The historical data set consists of the following variables: T(t-2), T(t-1), T(t), D(t-2), D(t-1), D(t). The output should be a prediction of the Recommended Retail Price (RRP) of electricity at the next time instant t+1, denoted by P(t+1). You have been provided with real-world electricity pricing data from Queensland, Australia. There are two datasets: a training set, to be used for model development; and a test set, to be used to evaluate the performance of your models. Each dataset has the same structure. Rows correspond to successive time instants, and contain seven values: the predictor variables T(t-2), T(t-1), T(t), D(t-2), D(t-1), D(t), and the target variable P(t+1). The objective is to predict the value of P(t+1) on the basis of one or more of the six predictor variables. There are five parts to the assignment, described below, with the approximate assessment weighting. Parts 1, 2 and 3 are based on content that has been covered up to then end of Week 5. Content for Part 4 will be covered in Week 6 and 7. |

| Question | 3. The stocking system is updated daily at 11:59 pm. This number has been consistent every day until the beginning of a new financial year. At the beginning of the new financial year each year (15t July), the company will impose a 10% increase in the supply of cantilever umbrellas to its distributors (rounded up) and 5% increase of the RRP due to inflation. 1. Based on statistics, global financial crisis happens every 9 years, and lasts for another 2 years, the number of cantilever umbrella distributed to distributors will drop by 20% in the first year when global financial crisis hit the market, the number will continue to drop by 10% and 5% for the next 2 years when the economy is recovering. In order to make up the losses, during the year that a global financial crisis starts, the company will add an additional 10% increase in RRP to the product, the increase of the product RRP will become 5% in the next year, and 3% the year after to make up the loss. |

Order the answer to: Arsenic enters drinking water supplies from natural deposits in
| Question | Arsenic enters drinking water supplies from natural deposits in the earth or from agricultural and industrial practices. Since it has been linked to cancer of the bladder, kidney, and other internal organs, the EPA has lowered the arsenic standard for drinking water from 0.050 parts per million to 0.010 parts per million (10 parts per billion). The annual cost to public water utilities to meet the new standard is estimated to be $200 per household. If it is estimated that there are 90 million households in the United States and that the lower standard can save 50 lives per year valued at $4,000,000 per life, what is the benefit/cost ratio of the regulation? |

Order the answer to: The cost of grading and spreading gravel on a short
| Question | The cost of grading and spreading gravel on a short rural road is expected to be $300,000. The road will have to be maintained at a cost of $25,000 per year. Even though the new road is not very smooth, it allows access to an area that previously could only be reached with off-road vehicles. The improved accessibility has led to a 150% increase in the property values along the road. If the previous market value of a property was $900,000, calculate the B/C ratio using an interest rate of 6% per year and a 20-year study period. |

| Question | Buster County has proposed a strict water conservation policy for all industrial plants within the county limits. Enforcement is proposed to be a public-private between the sheriff’s office and a private security company. In preparing for a B/C analysis of the proposal, estimates must be categorized as a benefit, cost, or disbenefit. The categories chosen will vary depending upon a person’s viewpoint. Assume that possible viewpoints include sales revenues, politics, service to the public, the environment, contract obligations, future generations of residents, legal matters, revenue and budget (in general), and customers. Select the top two viewpoints (in your opinion) for each of the following individuals as they would categorize estimates as a cost, benefit, or disbenefit. 1. An industrial plant manager in the county 2. County sheriff’s deputy (appointed office) 3. County commissioner (elected office) 4. Security company president |
