One of your friends is comparing yeast fermentation rates when yeast is grown in a solution containing glucose (G) and when grown in a solution containing starch (S). The friend starts with no expectations about which feeding medium will give higher yields but after seeing the results of the experiment, in which fermentation rates were higher for the glucose medium, formulates the hypotheses as H0: µG = µS against H1: µG > µS. Are these hypotheses appropriate?
