### 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.
