# Stats (Chi-Square)

Suppose you have a chi-squars GOF test to test null hypothesis that the age distribution of drivers stopped in 2003 for traffic violations is the same as the age distr. in 2002. You compute chi-square= 14.7. At the 5% significance level, what is an appropriate conclusion?

A p-value is less than .05
B p is greater than .05
C Because the conditions for a chi-square GOF test aren't satisfied, you cant' draw an appropriate conclusion.

What does it mean for your p-value if you have a big or small chi-square?
