Explanation / Answer

1) Range = 150 - 129 = 21

2) mean = (0 + 71 + 93 + 168 + 191 + 194 + 224 + 230 + 234 + 249 + 256 + 266 + 332 + 374 + 387)/15 = 217.93

Variance = ((0 - 217.93)^2 + (71 - 217.93)^2 + (93 - 217.93)^2 + (168 - 217.93)^2 + (191 - 217.93)^2 + (194 - 217.93)^2 + (224 - 217.93)^2 + (230 - 217.93)^2 + (234 - 217.93)^2 + (249 - 217.93)^2 + (256 - 217.93)^2 + (266 - 217.93)^2 + (332 - 217.93)^2 + (374 - 217.93)^2 + (387 - 217.93)^2)/14 = 11400.1
