For the horseshoe crab data , fit the logistic regression model for π =probability of a satellite, using weight as the predictor. a. Report the ML prediction equation. b. Findat the weight values 1.20, 2.44, and 5.20kg, which are the sample minimum, mean, and maximum. c. Find the weight at which. d. At the weight value found in (c), give a linear approximation for the estimated effect of (i) a 1kg increase in weight. This represents a relatively large increase, so convert this to the effect of (ii) a 0.10kg increase, and (iii) a standard deviation increase in weight (0.58kg). e. Construct a 95% confidence interval to describe the effect of weight on the odds of a satellite. Interpret. f. Conduct theWald or likelihood-ratio test of the hypothesis that weight has no effect. Report the P-value, and interpret. Note: you can get the data in the R package "icda" which is named by "horseshoecrabs".

听力原文： Hello, I'll be your tour guide today here at the art museum so I'd like to welcome you m this month's exhibit on native American pottery. We'll begin our tour in a few minutes. But first I'm going to tell you something about the way this pottery was created. Pottery was made all over ancient North America by many different groups of people. One of the earliest of these ancient American cultures was the Hohokam people. They lived in what is now Arizona from about 300 BC to 1500 AD. And it's their pottery that you will be looking at today. All of the pottery was made from clay. Some objects were for everyday use, like con miners for food and water: pots for cooking, and mugs, bowls and ladles for drinking and eating. You will also sec finger rings and animalshaped incense burners, which we believe were probably used in special rituals. The Hohokam formed their pottery vessels from coils of clay. They then shaped them with special tools to create very thin sides on the vessels. Afterwards they painted the pottery with red designs. Actually many of the pieces here have designs right on them that show how the pottery was used. Now I hope you'll enjoy the beauty and the uniqueness of the Hohokam pottery and this will give you some interesting insight about the people who created it. Please feel free to ask me any questions and thank you for joining us today.

When describing a chart/figure/table, you are advised to follow four stages. Stage 1: Introduce the topic: Describe the general topic the chart/figure/table concerns, and give background information. Stage 2: Explain what the chart/figure/table shows and briefly expand on the title of the chart/figure/table by providing more details, such as what is shown by each axis on a graph, or each column in a table. Stage 3: Highlight the information of particular interest or relevance, focusing on a new aspect of the information. Stage 4: Comment on the information by emphasising the significance of the information to the essay or report more generally, or on the limitations of the information. The following sentences are taken from a report on Global Greenhouse Gas Emissions Data. The pie chart shows the emissions by countries. Identify the corresponding stages of the sentences describing the chart and re-order them to make the description logical.Source: Boden, T.A., Marland, G., and Andres, R.J. (2015). National CO2 Emissions from Fossil-Fuel Burning, Cement Manufacture, and Gas Flaring: 1751-2011, Carbon Dioxide Information Analysis Center, Oak Ridge National Laboratory, U.S. Department of Energy, doi 10.3334/CDIAC/00001_V2015 ❶ These data include CO2 emissions from fossil fuel combustion, as well as cement manufacturing and gas flaring. ❷ Together, these sources represent a large proportion of total global CO2 emissions. ❸ In areas such as the United States and Europe, changes in land use associated with human activities have the net effect of absorbing CO2, partially offsetting the emissions from deforestation in other regions. ❹ In 2011, the top carbon dioxide (CO2) emitters were China, the United States, the European Union, India, the Russian Federation, Japan, and Canada. ❺ However, changes in land use can be important: estimates indicate that net global greenhouse gas emissions from agriculture, forestry, and other land use were over 8 billion metric tons of CO2 equivalent, or about 24% of total global greenhouse gas emissions. ❻ Emissions and sinks related to changes in land use are not included in these estimates. Order the sentences in the following form: 2-3-1-4...

Some 60 years ago, George Orwell wrote an allegorical novel, called Nineteen Eighty-Four , to describe life in a futuristic Britain under a one party police-sate presided over by an all-powerful figure known as Big Brother. One of the fealures of the nasty world described by Orwell was its systematic misuse of language, which went by the name of “Newspeak”. By re-defining words and endlessly repeating them, the Ministry of Truth through the Thought Police was able to control what people thought, and through that, their actions. Language was instrumental in destroying the culture.

The same technique is being used by different people today, with similar effects. In all areas of public administration, the words “spouse”, “husband” and “wife” have been replace by the word “partner”, although the words are subtly but substantially different in meaning, and convey different realities. In some schools and university departments, feminist ideologues have dictated that the personal pronoun “he” must not be used, and is replaced by the word “they”, which means something different. The word “homophobic”, which just a few years ago was used to describe a person who supported vigilante action against homosexuals, is now being used to describe anyone who defends the universal definition of marriage.

Although the transformation of language is seen most obviously around social issues, it is also being used systematically to shape political debate. So, we are told that the federal government is introducing a Carbon Pollution Reduction Scheme, which is newspeak for its new carbon tax. The fact is that the new tax is not remotely concerned with “carbon pollution ” at all, but rather with emissions of the gas CO2 which is not a pollutant by any credible definition, but rather, an essential building block in every cell in every living plant and creature. By the government ’s own admission, it will not lead to any reduction in CO2 levels, either in Australia or globally. And the Carbon Pollution Reduction Scheme is being introduced in Australia at the same time the government is expanding exports of coal, which is virtually 100 percent carbon, to countries such as China.

We live in a society in which the ordinary meaning of words is being systematically manipulated by spin-doctors and ideologues, as a means of changing the way people think, and, more fundamentally, the way they act. Language is an important part of the culture wars. For those of us who see this as a challenge to the foundations of society, it is important that we identify the problem and expose it.

It is clearly preferable to avoid using the new debased, transformed language of the politically-correct left, although this can be difficult in situations where constant usage has already normalized it, as has happened with the term “same-sex marriage”. The alternative phrase, “same-sex unions”, has a different meaning. When such terms are used, they should be identified for what they are: a form. of linguistic dishonesty, designed to undermine existing institutions and transform. them.
