Barbara claims that her horse can do simple addition problems. she showed her horse eight different cards with simple addition problems, and the horse was able to tap his foot to indicate whether the answer was correct or incorrect. the horse correctly identified all eight cards. eric didn't believe barbara's horse could do addition, so he set up a trial to test whether the horse was just guessing. he flipped eight coins to see how many would land tails up. he did this 53 times, and the results are shown in the dot plot below: a dot plot with values of 1, 2 3, 4, 5, 6, 7, 8 corresponding to frequencies of 3, 5, 8, 11, 8, 7, 5, and 1 respectively. based on these results, can barbara's horse add?
