According to scientists, the cockroach has had 300 millionyears to develop a resistance to destruction. In a study conductedby researchers 6.000, roaches (the expected number in aroach-infested house) were released in the test kitchen. One weeklater, the kitchen was fumigated and 21,425 dead roacheswere counted, a gain of 15,425 roaches for the 1-weekperiod. Assume that none of the original roaches died during the1-week period and that the standard deviation of x, the number ofroaches produced per roach in a 1-week period, is 1.3 Use thenumber of roaches produced by the sample 6,000 of roaches to find a99% confidence interval for the mean number of roaches producedper week for each roach in a typical roach-infested house.
