I NEED HELP ASAP!! Martha has determined, through scientific investigation, that pigs prefer warm mud over cold mud. Martha watched her pet pig, Porky, and Porky chose the warm mud every time. Has Martha reached a valid conclusion?
A) No. The sample size is too small.
B) Yes. Porky confirmed her hypothesis.
C) No. It has already been determined that pigs like warm mud.
D) No. The results cannot be valid because Martha is not a real scientist.
