Every morning the foreman flips a coin to decide which group ofplanters get first choice of the day's planting sites. You thinkthe foreman doesn't like your group (we won't go into the reasonswhy, but your suspicions are well-founded) and that he's riggingthe coin tosses against your group. You keep track for 12 days andnote that 10 of the 12 coin tosses have gone against your group.Test the hypothesis (at α=.05) that the foreman is rigging the cointosses.
