A scientist who works for a pesticide manufacturer conducts an experiment to test the toxicity of a new herbicide. She prepares six solutions containing different concentrations of the pesticide and six test groups, and each test group contains 70 weeds. She then sprays each test group with one of the solutions and records the number of weeds that die within 48 hours. The scientist records the results of her experiment in this table.

In your notebooks, create a semi-log graph showing the dose-response curve for the new herbicide. Based on the scientist’s experiment, approximately what is the herbicide’s LD50? Is the new herbicide more or less potent than an herbicide with an LD50 of 0.001 percent? Explain your answer. (8 points)
