PCB contamination of a river by a manufacturer is being measured by the amount of the pollutant found in fish. A company scientist claims that the fish contain only 5 parts per million, but an investigator believes the figure to be higher. A sample of 6 fish are collected and the PCB measured. Is there evidence at the 0.05 significance level that the investigator’s claim is correct? 6.8, 5.6, 5.2, 4.7, 6.3, 5.4
