In the nuclear industry, detailed records are kept of the quantity of plutonium received, transported, or used. Each shipment of plutonium pellets received is carefully analyzed to check that the purity and hence the total quantity is as the supplier claims. A particular shipment is analyzed with the following results: 99.93, 99.87, 99.91, 99.86%. The listed purity as received from the supplier is 99.95%. Is the shipment is not rejected at 95% confiedence level?
