is in the appendix section. Its aim is to find out what kind of factors matters to the people who are considering buying a car according to the theories of consumer behavior.
With the materials we collected, we will propose an overall suggestion to make the hybrid car market enjoy a favorable business climate. Not only the earth will welcome it but also our offspring will too.

Data description
2.1 Variable selection
Our group started to think about the various factors that can be representative of the socio-economic elements considering the interrelationship with IQ scores. Finally, we selected 8 variables to explain the differences of IQ scores among the countries: GDP per capita, happiness index, duration of education, life expectancy, urbanization, corruption pe
Ⅰ. Introduction
1) Location
Russia is located in the north Eurasia continent (Far East Asia ~ Europe). Russia is the largest country in the world which is about 1/8 of the world’s land area. Because of this huge territory, there is an 11-hour time difference between East and West.
2) Climate
The huge territory of Russia also makes a various climate zone. Basically, Russia has continental
This idea can be applied to logistics as well. In the past, logistic cost has been defined in purely monetary terms. However, as not only in the EU but also in the USA and other countries became more and more aware of environmental problems ,for instance because of climate change, air pollution, noise and accidents, environmental considerations has been taken in logistics kfield. This is how Gree
data collected by Korea Expressway Corporation (Jan., 02, 2000-Dec., 31, 2000), basic condition including accident time, day of the week, climate, sunlight, road condition including division of road pavement, road facility around the accident location, road protective facility, road surface condition, traffic restriction condition, accident direction, division of workplace and number of damaged f

For example, there is Korean KS criterion, which divides the body type into the size of drop value, gap of hip girth and waist girth. (N: Normal type, A: Small breast and big hip, H: Big breast and small hip). These basic data for garment size specificatio

normal distribution, so we can use z-distribution instead of t-distribution.
If α=0.05, the null hypothesis cannot be rejected because the p-value, 0.211, is bigger than α, which means there is no difference of coffee amount between upper and lower classes.
Besides, because the difference between the number of upper class(22) and the lower class(61) is quiet big, the data can be biased. If

1) Motivation
There is a famous economic idiom among economists in Korea that is ‘No Failure in Real Estate Market,’ which was coined from 1970s. However, that idiom was getting familiar to the normal investors from the last government after Asian financia

실제 현실 data를 이용해 추정을 해보면 오차항의 가정이 항상 normal이지 않을 뿐더러 오히려 logistic 분포나 다른 가정을 추가 혹은 완화했을 경우 더욱 효율적이고 유의적인 수준에서 추정치가 도출되곤 한다.
