Question: The circumferences of battery posts in a nickel-cadmium battery are Weibull-distributed with v = 3.25 centimeters, ß = 1/3, and a= 0.005 centimeters.
(a) Find the probability that a battery post chosen at random will have a circumference larger than 3.40 centimeters.
(b) If battery posts are larger than 3.50 centimeters, they will not go through the hole provided; if they are smaller than 3.30 centimeters, the clamp will not tighten sufficiently. What proportion of posts will have to be scrapped for one of these reasons?
