The beta of a firm is determined by three variables: (1)The type of business or business the firm is in (2)the degree of oper
data need to be collected. This is done through the Bus Management System (BMS). It was developed in 2005, becoming the first bus management system in Korea. The major function of BMS is the control of bus services by showing the current condition of bus operations, and the distance between the earlier and following buses to manage the time in which buses arrive at the bus stops. It does so by co

1) Purpose of project
Our purpose of this project is to use the knowledge we learned in the statistics management class and understand how to use these information to analyse the data we collected and depending our data to find the relationship between 3 variables we choose for proving the hypotheses we bring up are correct or not. Statisitics is a very important concept to many

올바르고 정확한 결과를 도출하기 위해서는 물론 전수 조사를 하면 가장 좋겠지만, 시간, 비용, 실제 시행가능성 등의 문제로 시행하기 어렵다. 그러므로 모집단을 가장 잘 대표할 수 있는 일정 표본을 선정하여 조사한 후
