A study was done to determine the effect of a chemical on
the likelihood of midges to emerge from the egg state. There were 20 midges per
replicate vessel composed of 10 males and 10 females, four replicates per
treatment in six positive concentrations of the chemical, and a water control.
Note that for each replicate vessel, where the number of a sex that emerged the
value of Rep j, j=1, 2, 3, or 4, does not sum to 10, the remaining number are
censored, i.e. did not emerge by the end of the study. The data are in Appendix
1 in the Excel file Time to Emergence  –  midge.xls.
