A MANUFACTURER OF HEATING APPLIANCES HAS A SUPPLIER THAT SUPPLIES IT WITH CERTAIN COMPONENTS WHICH HAVE AS SPECIFICATIONS A RESISTANCE OF 400 DEGREES CENTIGRADE TO HEAT. THE MANUFACTURER MAKES A RANDOM SELECTION OF 64 OF THESE COMPONENTS AND CHECKS THAT THEIR AVERAGE RESISTANCE TO HEAT IS 395 DEGREES CENTIGRADE, WITH A STANDARD DEVIATION OF 20 DEGREES CENTIGRADE. CAN YOU FIND THAT YOUR SUPPLIER DOES NOT SUPPORT THE AGREED SPECIFICATIONS, AT A LEVEL OF SIGNIFICANCE OF 5%?
