The formulae are often complicated‚ the calculations tedious‚ degrees of freedom mysterious‚ and probability tables confusing. But in fact students need no longer grapple with any of these.

shorter than TT Air‚ it does not significantly affect the output as the one day does not change much (unless there had been a market shock). However based on Central Limit Theorem‚ if the sample size is greater than or equal to 30 samples‚ the sample statistics reflect the time population parameters. • The Median data does not show much in this case as the range (4.7 AA Fly and 6.8 TT Air) is small for both AA Fly and TT Air. This means that the mean is more applicable to be used. • The Mode of AA

a) A company is interested in providing a new benefit to its employees to encourage them to utilize public transportation. To study the potential of providing this benefit‚ the company would like to do a survey of the workers at a company to gather information on why do or do not use public transportation for commuting to work. The company is about 25‚000 people in areas where public transportation is available. You also want to find out the reasons why their choice is what it is. In this case

Lecture 1. Descriptive statistics includes statistical procedures that we use to describe the population we are studying. The data could be collected from either a sample or a population‚ but the results help us organize and describe data. Descriptive statistics can only be used to describe the group that is being studying. That is‚ the results cannot be generalized to any larger group. Inferential statistics is concerned with making predictions or inferences about a population from observations

successful that after World War II many companies used similar techniques in managerial decision making and planning. The decision making task of modern management is more demanding and more important than ever. Many organisations employ operations research or management science personnel or consultants to apply the principles of scientific management to problems and decision making. In this module we focus on a number of useful models and techniques that can be used in the decision making process

Is the distribution symmetrical‚ positively skewed or negatively skewed? Explain your answer. - It is positively skewed because the mean is the largest of the three measures and the mode is the smallest of the three measures.

distribution function for 100 normal random numbers. The K-S test is based on the maximum distance between these two curves. Characteristics and Limitations of the K-S TestAn attractive feature of this test is that the distribution of the K-S test statistic itself does not depend on the underlying cumulative distribution function being tested. Another advantage is that it is an exact test (the chi-square goodness-of-fit test depends on an adequate sample size for the approximations to be valid). Despite
