The gambler rolled a die 120 times and observed frequencies that differed from the expected values of 20 for each outcome if the die was fair. A chi-square test was conducted to compare the observed and expected values. The results showed that the die was not fair at the 0.05 significance level but could not be rejected as unfair at the more stringent 0.01 level, as the observed chi-square value fell between the critical values for those levels.
