TRANSNATIONAL INVESTMENTS, INC. – QUESTIONS SUMMER 2016

 

 

 

In your report to your supervisor please include answers to the following five questions:

 

 

 

Q. 1.     Your data indicates that the stock market indices of all the countries studied increased between 2005 and 2006.  Unexpectedly, interest rates for all but one country also increased during that period.  Perhaps this is partially due to the positive inflation rates in all of these countries.         You would like to find out more information.  However, there are variations in the direction and in the size of these changes for each country and this complicates your analysis.

 

 

 

  1. The stock prices.xls Excel spreadsheetshows the change in stock market indices between 2005 and 2006 as a percentage of the 2005 indices.  It also shows the change in interest rates between 2005 and 2006 as a percentage of 2005 interest rates.  Use Excel to calculate the mean and standard deviation for the percent changes in market indices.  Perform the same calculations for the percent changes in interest rates.  What do these numbers indicate?

     

B. Conduct a hypothesis test to see if the mean percent change in stock market indices between 2005 and 2006 is significantly different from zero.  Do this without Excel.  Conduct the same test for the mean percent change in interest rates.  Use a significance of .03.  How do you interpret your findings?
