A simple model for the fraction of micropipets that operate within specifications after time t is where tm is the mean time between failure (the time when the fraction within specifications is reduced to 50%). Suppose that tm 2.00 years. (a) Show that the equation predicts that the time at which 50% remain within specifications is 2 yr if tm 2.00 yr. (b) Find the time t at which pipets should be recalibrated (and repaired, if necessary) so that 95% of all pipets will operate within specifications. 2
