The correct statement is that 95% of the tables for sample data from populations in which there is no relationship will have a chi-square statistic of less than 3.84, not greater. This is because a chi-square statistic of greater than 3.84 (at a significance level of 0.05) indicates that there is less than a 5% probability that the observed distribution is due to chance, suggesting a statistically significant relationship.
