Auto batteries have an average life of 2.7 years. Battery life is normally distributed with a mean

of 2.7 years and a standard deviation of .3 year. The batteries are warranted to operate for a

minimum of 2 years. If a battery fails within the warranty period, it will be replaced with a new

battery at no charge. The company sells and installs the batteries. Also, the usual $5 installation

charge will be waived.

company have to charge on its “premium” battery to offset the additional cost of replacing

batteries?

 

c. What other factors would you take into consideration besides the price of the battery?
