Chapter 6: Probability
... 1. Legitimate Values- 0≤P(A) ≤1 for any event A 2. Total Probability- P(S) =1 for the sample space S. 3. Addition rule: if events a and B are disjoint, then P(A or B) = P(A U B) = P(A) + P(B). 4. Complement rule: For any event A, P(Ac) = 1- P(A). 5. Multiplication rule : if events A and B are indepe ...

Consider the following data set:
... Since the data is right-skewed then the median is less than the mean. This is because a few data points on the right of the distribution pull up the mean. We have already discussed that the median of 52 is a better measure of the center of this data set. Definition: the kth-percentile ( Pk ) of a da ...
