Chi-Squared Homework Exercise

The following two links lead to data files for the Chi-Squared homework exercise we discussed in class.  The first link has the data in an Excel spreadsheet.  The second link has the same data in a text file.  The Excel spreadsheet also has a sample calculation showing how to calculate a cumulative normal probability using the built-in Excel function NORMSINV.  Using this function will save you the trouble of looking up values in the normal distribution tables.


Perform Chi-Squared test of the hypothesis that this data comes from a normal distribution.  I suggest that you use 5 cells for the Ch-squared test.  Your first cell should begin at  minus infinity, and the last cell should extend to infinity.
