In a study of jury behavior, Dr. Marek will obtain two samples of participants and give them details about a trial in which the defendant was obviously guilty. Although both groups will hear the same details during the trial, one group will be told that the judge withheld some evidence from the jury, while the other will not be told. Later the participants will be asked to recommend a jail sentence. Dr. Marek wants to see if the additional information (knowing that some evidence had been withheld) would affect the recommended sentence. The length of the sentence each participant recommended is presented in years in the chart below.

5) What does it mean (conceptually) to say thatp< .05 (i.e., thepvalue is less than .05 or 5%)?

The answer should start with "There is less than a 5% chance . . ."
