The lightbulbs in an industrial warehouse have been found to have a mean lifetime of 1030.0 hours, with a standard deviation of 90.0 hours. The warehouse manager has been approached by a representative of Extendabulb, a rompany that makes a device intended to increase bulb life. The manager is concerned that the average lifetime of Extendabulb-equipped bulbs might not be any greater than the 1030 hours historically experienced. In a subsequent test, the manager tests 40 bulbs equipped with the device and nds their mean life to be 1061.6 hours. Does Extendabulb reallyr work? Test the hypothesis at 5% level of significance
