In an experiment you do a chi-square test comparing observed and expected progeny. Your calculated chi square is 0.375. With 1 degree of freedom, this corresponds to a probability between 0.9 and 0.5. What does this mean? a. There is between a 50% and 90% chance that you did the experiment correctly. b.
