The mishandling of a shipping container loaded with 750 cases of wine caused some of the bottles to break. An insurance adjuster proposed to settle the claim at 20.8% of the value of the shipment, based on a random 250 bottle sample in which 14 were cracked or broken. Calculate the size of a random sampling needed for a relative standard deviation of 8%.
