there is not sufficient evidence to reject the null hypothesis. the significance level is probably 0.05 so a p-value of .3 is much larger so there is not enough evidence to reject the null hypothesis.

You don't state your null hypothesis, so you have no basis to reject it. Ordinarily, if the probability of an event described by the null hypothesis exceeds a certain probability (often, but not necessarily, 0.05 or 0.01) then one may not reject the null hypothesis. There is nothing to stop you from rejecting the null hypothesis any time the probability is less than 0.5, but you'd be wrong half the time in doing so.

ouch. you're making my head hurt.
I took statistics, but we never got as far as chi squares. good luck.
