One of your suppliers has belatedly realised that about 10% of the batches of a particular component recently supplied to you have a manufacturing fault that has reduced their reliability. There is no external or visual means of identifying thes substandard components. Battch identity has, however been maintained, so your problem is to sort batches that have this fault('bad batches') from the rest ('good batches'). An accelerated test has been devised such that components from good batches have a faliure...

The sample mean was 1.5 eggs/week and sample standard deviation was 0.3...
