Suppоse thаt а given dоse-respоnse experiment the dose of poison X аnd proportion m of insects out of M that are killed at each dose are given. A logistic regression model was used to model probability of killing insects [P(Y=1)]. Fitted logistic model is given by l o g i t ( P ( Y = 1 ) ) = β 0 + β 1 X . {"version":"1.1","math":"logit(P(Y=1))=beta_0+beta_1 X."} Compute the effective dose needed to kill 60% of the insect population.
