From the same survey referred to in Pronblem 1, Table 5.11 cross-classiﬁes whether a person smokes frequently with the four scales of the MBTI personality test. SAS reports model−2 log likelihood values of 1130.23 with only an intercept term, 1124.86 with also the main effect predictors, 1119.87 with also all the two-factor interactions, and 1116.47 with also all the three-factor interactions. a. Write the model for each case, and show that the numbers of parameters are 1, 5, 11, and 15. b. According to AIC, which of these four models is preferable？ c. When a classiﬁcation table for the model containing the four main effect terms uses the sample proportion of frequent smokers of 0.23 as the cutoff, sensitivity = 0.48 and speciﬁcity = 0.55. The area under the ROC curve is c =0.55. Does knowledge of personality type help you predict well whether someone is a frequent smoker？ Explain. From the same survey referred to in Pronblem 1, Ta

Task 2

Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45.

British university entrants(新学员) expect to be provided with washing machines and dryers in their rooms, and even car parking spaces, a survey has found. Students are also less prepared to tolerate poor quality living conditions than their predecessors, says the survey by British polling organization Mori.

More than 1,000 full-time undergraduates and postgraduates from 21 universities across the UK were surveyed for the research. It shows that location is the key factor in choosing accommodation for students—nearly half of those interviewed said that being close to their place of study was the most important factor in their choice. Cost came second, with evidence that many parents foot the bills for their children's rent. The survey also shows that students are no longer prepared to carry bags of washing to the nearest launderette(自动洗衣店). These newcomers expect washers and dryers to be provided with their accommodation. The study also highlights those things today's students expect as standard—communal (公共的) areas to be cleaned regularly, utility bills to be included, even private car parking space to be included.

Separate findings from the UK's National Union of Students published earlier this year show more than half of students in private rented accommodation are living in unsatisfactory conditions.

Who are the subjects of the survey？

A．Some oversea students in UK.

B．Some undergraduates and postgraduates in UK universities.

C．Some graduates in UK universities.

D．Some British students in other countries.

A random sample of shoppers responded to the questions contained in a marketing survey. Si

x months later, another random sample of shoppers responded to exactly the same questions, except that the questions were now arranged in a different order. The pattern of responses to many individual questions was greatly different, thus demonstrating that a question will sometimes elicit different responses depending only on what question precedes it. The argument above depends on which of the following assumptions？

A．The reordering of the questions did not put each question in a different sequential position from its position six months previously.

B．Shoppers who respond to a marketing survey do not generally remember six months later what responses they gave.

C．There was no motive for the second survey except that of discovering whether the ordering of the questions mattered.

D．The survey was not composed of questions to which shoppers would give different responses at different times of the year.

E．The first sample of shoppers did not have any individuals in common with the survey sample of six months later.

第3篇 Attitudes to AIDS Now Most people say that the USA is making progress in fighting

AIDS, but they don\'t know there\'s no cure and strongly disagree that \"the AIDS epidemic is over,\" a new survey finds. The findings, released Thursday by the Kaiser Family Foundation, reassure activists who have worried that public concern about AIDS might disappear in light of recent news about advances in treatment and declines in deaths. \"While people are very optimistic about the advances, they\'re still realistic about the fact that there is no cure\" says Sophia Chang, director of HIV programs at the foundation. The Kaiser survey, like a recent USA TODAY Gallup Poll, does find that the number of people ranking AIDS as the country\'s top health problem has fallen. In the Kaiser Poll, 38% say it\'s the top concern, down from 44% in a 1996 poll; in the Gallup Poll, 29% say AIDS is No.1, down from 41% in 1992 and 67% in 1987. Other findings from Kaiser, which polled more than 1,200 adults in September and October and asked additional questions of another 1,000 adults in November: 52% say the country is making progress against AIDS, up from 32% in 1995.51% say the government spends too little on AIDS. 86% correctly say AIDS drugs can now lengthen lives; an equal number correctly say that the drugs are not cures.67% incorrectly say that AIDS deaths increased or stayed the same in the past year; 24% know deaths fell.

Attitudes to AIDS Now

Most people say that the USA is making progress in fighting AIDS, but they don't know there's no cure and strongly disagree that "the AIDS epidemic is over," a new survey finds.

Task 2Directions: This task is the same as Task 1.The 5 questions or unfinished statements

Task 2

Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45.

At least 2.3 million people took some kind of online course in 2004, according to a recent survey by The Sloan Consortium, an online education group, and two-thirds of colleges offering "face-to-face" courses also offer online ones. But what were once two distinct types of classes are looking more and more alike--and often dipping into the same pool of students.

At some schools, online courses--originally intended for nontraditional students living far from campus--have proved surprisingly popular with on-campus students. A recent study by South Dakota's Board of Regents found 42 percent of the students enrolled in its distance-education courses weren't so distant: they were located on campus at the university that was hosting the online course.

Numbers vary depending on the policies of particular colleges, but other schools also have students mixing and matching online and "face-to-face" credits. Motives range from lifestyle. to accommodating a job schedule to getting into high-demand courses.

Washington State had about 325 on-campus undergraduates taking one or more distance courses last year. As many as 9,000 students took both distance and in-person classes at Arizona State last year.

The first paragraph mainly tells us that ______.

B．online courses are becoming more important than traditional courses

C．online courses were different from traditional courses

D．online courses are becoming more popular in college education

E．online courses are actually not different from traditional courses
