Question: A consumer electronics firm has developed a new type of remote control button that is designed to operate before becoming intermittent. A random sample of 25 of new buttons resulted in a mean of 1,241.2 hours of continuous service with a standard deviation of 110.8 hours. The current best remote control button in the market has a mean life of 1200 hours. Can we conclude that the new remote control button is superior to the current best product in the market at a 95% confidence level?
