A random sample of twenty female adults was obtained. The data below is the weight measured in pounds and systolic blood measured in mmHg. pressure Weight Blood Pressure Weight Blood Pressure 180 138 145 120 175 135 156 125 195 140 135 110 171 129 140 115 160 126 115 108 158 128 149 124 162 130 135 114 150 135 130 105 194 142 130 117 150 127 120 102
