Question

Researchers at Pennsylvania State University conducted experiments with poplar trees. Listed below are weights (kg) of poplar trees given no treatment and poplar trees treated with fertilizer and irrigation. Find the range, SD, and variance of both datasets. Does there appear to be a difference between the two standard deviations? No treatment: 0.16, 0.03, 0.17, 0.38, 0.23 Fertilizer and irrigation: 2.04, 0.28, 0.93, 1.08, 2.39
