A data frame of a toxicity trial.
A data frame with 6 observations on the following 3 variables.
a numeric vector, percent concentration of pyrethrins.
number of eggs that hatched.
number of eggs that did not hatch.
Finney (1944) describes a toxicity trial of five different concentrations of pyrethrins (percent) plus a control that were administered to eggs of Ephestia kuhniella. The natural mortality rate is large, and a common adjustment is to use Abbott's formula.
