EXPLAIN why each of the following statements is either true or false:

(a) The computer program gave me a p-value of 0.000, so I know that my theory has been verified.

(b) The computer program gave me a p-value of 0.02, so I know that I have found a very strong relationship.

(c) The computer program gave me a p-value of 0.07, so I know that this relationship is due to random chance.

(d) The computer program gave me a p-value of 0.50, so I know that there is only a 50 percent chance of this relationship being systematic.
