太傻gre阅读题一篇
the hypothesis of an expanding earth has never attracted notable support,and if it were not for the historical example of continental drift,such indifference might be a legitimate response to an apparently improbable concept.it should be remembered,however,that drift too was once regarded as illusory,but the idea was kept alive until evidence from physicists compelled geologists to reinterpret their data.
of course,it would be as dangerous to overreact to history by concluding that the majority must now be wrong about expansion as it would be to reenact the response that greeted the suggestion that the continents had drifted.the cases are not precisely analogous.there were serious problems with the pre-drift world view that a drift theory could help to resolve,whereas earth expansion appears to offer no comparable advantages.if,however,physicists could show that the earth’s gravitational force has decreased with time,expansion would have to be reconsidered and accommodated.
1.the passage indicates that one reason why the expansion hypothesis has attracted little support is that it will not
(a) overcome deficiencies in current geologic hypotheses
(b) clarify theories concerning the earth’s gravitational forces
(c) complement the theory of continental drift
(d) accommodate relevant theories from the field of physics
(e) withstand criticism from scientists outside the field of geology
2.the final acceptance of a drift theory could best be used to support the argument that
(a) physicists are reluctant to communicate with other scientists
(b) improbable hypotheses usually turn out to be valid
(c) there should be cooperation between different fields of science
(d) there is a need for ***al control of scientific research
(e) scientific theories are often proved by accident
3.in developing his argument,the author warns against
(a) relying on incomplete measurements
(b) introducing irrelevant information
(c) rejecting corroborative evidence
(d) accepting uninformed opinions
(e) making unwarranted comparisons
4.it can be deduced from the passage that the gravitational force at a point on the earth’s surface is
(a) representative of the geologic age of the earth
(b) analogous to the movement of land masses
(c) similar to optical phenomena such as mirages
(d) proportional to the size of the earth
(e) dependent on the speed of the earth’s rotation

求大神帮助!Hypothesis Test two sample test question
题目如下：
The agency has always valued houses higher if they are primarily made of brick. In fact
they usually add on an extra $15000 to the valuation if it is a brick house.
Separate the data into two groups. Group 1: Brick houses; Group 2: Non-brick houses.
i.Fully investigate the hypothesis that brick houses sell for more money on
average than non-brick houses. State all required assumptions, indicate your
chosen level of significance (and why you chose it) and give a plain-English
conclusion.
ii.Test the agency’s hypothesis that $15000 should be added to the valuation of
brick houses. Does the sales data support that?

Hypothesis 2,which predicts that decision com-prehensiveness will act as a mediator,received par-
tial support.As shown in model 2 of Table 3,the regression of decision comprehensiveness on pre-
dictors revealed that the interaction of debate and education diversity was positively associated with
x09x09x09x09x09x09
decision comprehensiveness (3 = .20,p < .10),as was the debate-by-tenure-diversity interaction
(f3= .36,p < .01).As shown in model 3,decision comprehensiveness predicted change in profitabil-
ity (3 = .37,p < .01) and change in sales (8 = .42,
p < .01).A comparison of the interactions in model
1 with the interactions in model 3 shows support
for a partial mediating effect.Adding decision comprehensiveness as a predictor in the performance
regressions diminished the effects of debate crossed with education diversity and debate with
tenure diversity on change in profitability and change in sales.This result suggests that decision comprehensiveness partially mediates the effects
on firm performance of the interactions of debate and education diversity and of debate and tenure diversity.
Hypothesis 3 predicts that interactions between more job-related forms of diversity and debate will have stronger positive effects on decision compre-
hensiveness and firm performance than will inter- actions between less job-related forms of diversity
and debate.
