Interpret the level of statistical significance for the event described.
-A study of 600 college students taking Statistics 101 revealed that 59 students received the grade of A.
Typically 10% of the class gets an A. The difference between this group of students and the expected value is not significant at the 0.05 level. What does this mean in this case?
A)The probability that the difference occurred due to chance is more than 0.05.
B)The probability that the difference occurred due to chance is less than 0.05.
C)There is not enough information to make any conclusion.
D)The probability of getting an A is 10% and only 9% got an A in this study. The difference is less than 5% so it is not significant.

The statement means that the observed difference between the actual number of students who got an A and the expected number (based on the typical 10% rate) could easily have happened by random chance, with a probability higher than 5%. This implies that the observed outcome does not provide strong enough evidence to suggest a significant deviation from the norm.
