The term statistically significant means having a probability of less than __________ that the results are due to random chance.

A) 3%
B) 5%
C) 8%
D) 15%

A common threshold for statistical significance is a probability of less than 5% (p<0.05). This means that there is a 5% or less chance that the results are due to random chance. Therefore, option B (5%) is the correct answer. The other options (3%, 8%, 15%) are not commonly used thresholds for statistical significance.
