a) Plant A: $52, 54, 54, 57, 58, 61, 63, 64$ mode = most often 54 shows up twice in the set median = middle $52, 54, 54, 57, 58, 61, 63, 64$ $54, 54, 57, 58, 61, 63$ $54, 57, 58, 61$ $57, 58$ $57.5$ mean = average $(52+54+54+57+58+61+63+64)/8$ $463/8 = 57.875$ range = max - min range = 64- 52 range = 12 Plant B: $43, 45, 49, 52, 57, 63, 64, 72$ mode = most often No mode as all data points are listed once median = middle $43, 45, 49, 52, 57, 63, 64, 72$ $45, 49, 52, 57, 63, 64$ $49, 52, 57, 63$ $52, 57$ $(52+57)/2 = 54.5$ range = max- min range = 72-43 range = 29 mean = average $(43+45+49+52+57+63+64+72)/8$ $445/8$ $55.625$
