Loads at which '10 amp' fuses fail

Use this diagram to introduce the idea of estimating the parameters to get the logistic curve 'close' to the data.

Drag the two red arrows to change the logistic curve's parameters.

Click Best fit to show the best (maximum likelihood) estimates. State that a computer will find the best estimates but the underlying details are fairly advanced.

A company manufactures fuses that are designed to blow when a current of 10 amps flows through them. Batches of one hundred fuses were tested at currents of 9 amps, 9.5 amps, ..., 11.5 amps and failures were noted.
