Interpret the level of statistical significance for the event described.

A study of students taking Statistics 101 was done. 500 students who studied for more than 10 hours averaged a B.  250 students who studied for less than 10 hours averaged a C.  This difference was significant at the 0.01 level.  What does this mean?
◦ The probability that the difference was due to chance alone is greater than 0.01.
◦ There is less than a 0.01 chance that the grades were better by chance alone.
◦ The improvement was due to the fact that more people studied.
◦ There is not enough information to make any conclusion.
