I bought a Honda CR-V the other day and my neighbor bought a Ford Escape. Honda says the CR-V will last an
average of 8 years with a standard deviation of 1.1 years. Ford says the Escape lasts longer, with an average life expectancy of 9 years and a standard deviation of 1.3 years. Which car, on average, is relatively more reliable?
a.The two cars are equally reliable
b.It is not possible to calculate relative reliability
