According To Scientists The Cockroach Has Had 300 Million Years To Develop A Resistance To Destruction In A Study Cond 1 (41.55 KiB) Viewed 21 times

According to scientists, the cockroach has had 300 million years to develop a resistance to destruction. In a study conducted by researchers, 6,000 roaches (the expected number in a roach-infested house) were released in the test kitchen. One week later, the kitchen was fumigated and 19,501 dead roaches were counted, a gain of 13,501 roaches for the 1-week period. Assume that none of the original roaches died during the 1-week period and that the standard deviation of x, the number of roaches produced per roach in a 1-week period, is 1.4. Use the number of roaches produced by the sample of 6,000 roaches to find a 95% confidence interval for the mean number of roaches produced per week for each roach in a typical roach-infested house. Find a 95% confidence interval for the mean number of roaches produced per week for each roach in a typical roach-infested house. (Round to three decimal places as needed.)
