Question
Select the THREE statements about probabilities and p-values given below which are TRUE. Select one or more: In hypothesis testing, a p-value of less than 0.0005 means there is very strong evidence against the null hypothesis. Suppose A and B are two statistically independent events. If P(A) = 0.3 and P(B) = 0.6 then P(A and B) must be equal to 0.18. If event A is more likely than event B, then P(A) is less than P(B). The value 0.42 is a valid value for a probability. The value 1.983 is a valid value for a p-value. If A and B are mutually exclusive events then P(A or B) must be equal to zero.
