Question

A BearVault BV canister manufacturer makes a type of lid to beused for these airtight food containers. the manufacturer needs tobe sure that all of its lids are very similar in diameter ,so itsets an upper tolerance limit for the variance of lid diameter at0.05mm. A random sample of 28 lids yields a variance of 0.015 mmfor lid diameter. Test the manufacturer's claim that the vriance isless than 0.05mm at the =0.005 level. What can youconclude?
