TAILIEUCHUNG - Lecture Statistical techniques in business and economics: Chapter 15 - Lind, Marchal, Wathen

Chapter 15 - Chi-square applications, when you have completed this chapter, you will be able to: Understand the nature and role of chi-square distribution, identify a wide variety of uses of the chi-square distribution, conduct a test of hypothesis comparing an observed frequency distribution to an expected frequency distribution,. | Index Numbers Chapter 15 GOALS Describe the term index. Understand the difference between a weighted and an unweighted index. Construct and interpret a Laspeyres price index. Construct and interpret a Paasche price index. Construct and interpret a value index. Explain how the Consumer Price Index is constructed and interpreted. Index Numbers INDEX NUMBER A number that measures the relative change in price, quantity, value, or some other item of interest from one time period to another. SIMPLE INDEX NUMBER measures the relative change in just one variable. EXAMPLE According to the Bureau of Labor Statistics, in January 2000 the average hourly earnings of production workers was $. In March 2008 it was $. What is the index of hourly earnings of production workers for March 2008 based on January 2000? An index can also compare one item with another. Example: The population of the Canadian province of British Columbia in 2007 was 4,352,798 and for Ontario it was .
