If P(A) = 0.62, P(B) = 0.47, and P(A u B) = 0.88; then P(A n B) = O 0.2914 O 0.6700 O1.9700 O 0.2100 If P(A) = 0.85, P(A U B) = 0.72, and P(A n B) = 0.66, then P(B) = O 0.28 O 0.53 O 0.15

O 0.15

If A and B are Independent events with P(A) = 32% and P(B) E 45.6%, then P(AUB) (Hint: Put Answer = 0 if it is not possible to calculate because not enough informatian is provided)

Doubling the size of the sample will O double the standard error of the mean O reduce the standard error of the mean to approximately 70% of its current value O reduce the standard error of the mean to one halfits current value O have no effect on the standard error of the mean
