Example 2: The following table shows the observed frequencies
in tossing a die 120 times. x° can be used to test if the die is fair. (df
=5.) Note: Assume that the expected frequencies are equal.

The value of x? for df =5 and 5% significance (found on p. 438 of
Freund's Mathematical Statistics, 2nd edition)is 11.070. Since 5.00
is less than 11.070, no statistically significant differences exist
between the observed and expected frequencies.
