5) A student was performing an experiment that compared a new protein food to the old food for goldfish. He
found the mean weight gain for the new food to be 12.8 grams with a standard deviation of 3.5
grams. Later he realized that the scale was out of calibration by 1.5 grams (meaning that the
scale weighed items 1.5 grams too much). What should the mean and standard deviation be for
the new food?
