Chapt 4, Q8: Answer this question please The antibody production of 12 male red-winged blackbirds before and after receiving testosterone implants was compared. The units for antibody levels were natural log (10-3 optical density) per minute (ln(mOD/min)). The mean change in antibody production was d = 0.056, and the standard deviation was sd = 0.240 If you were assigned the task of repeating this experiment, and wanted to ensure that you could detect a mean change of 0.08 units with a probability of 0.8, then what sample size would you use? Since we are calculating n for a study of individuals, answers should be rounded to the closest whole number.

Q: please highlight the correct answer at the end
