A farmer hypothesizes that a new agricultural fungicide will increase the yield of apples in her orchard. She selects tan apple trees at random. The leaves and branches on one side of each tree are sprayed with the fungicide; the other side of each tree is not sprayed and serves as a control. At harvest time the yield of apples from each side of each tree is determined. The data are shown below. Yield (kg) - Yield (kg) - Tree # sprayed branches unsprayed branches 1 134 130 2 136 128 3 117 117 4 122 115 5 129 124 6 107 98 7 127 14 8 120 120 9 132 134 10 130 126 Mean: 125.4 110.6 Standard deviation: 8.92 35.4 Did the fungicide increase the yield of apples?
