Multiplication Rule For Expected Value
Independence for Random Variables:
Two random variables X and Y are independent if and only if P(X, Y) = P(X)P(Y).
Independence is a stronger property than uncorrelatedness because correlation addresses only linear relationships.
Multiplication Rule for expected value of the product of uncorrelated random variables.
If X and Y are uncorrelated: E(XY) = E(X)E(Y)
p-Value:for rejecting the null is strongest for Test 3.
Rejection Point (Critical Value) for the Test Statistic:the result is not statistically significant at the 0.05 level.
The Total Probability Rule:not-S,the two-quarter period in total.rulejoint probability of both A and B occurring is PAB = PAPB.
