Two machines are used for filling plastic bottles with a netvolume of 16.0 ounces. The filling processes can be assumed tobe normal, with standard deviation of1 = 0.015 and2 = 0.018. The quality engineeringdepartment suspects that both machines fill to the same net volume, whether or not this volume is 16.0 ounces. An experiment isperformed by taking a random sample from the output of eachmachine.
