A New Apparatus Has Been Devised to Replace the Needle $\alpha = 10$

A new apparatus has been devised to replace the needle in administering vaccines. The apparatus, which is connected to a large supply of vaccine, can be set to inject different amounts of the serum, but the variance in the amount of serum injected to a given person must not be greater than .05 to ensure proper inoculation. A random sample of 25 injections resulted in a variance of .118. Specify the rejection region for the test. Use $\alpha = 10$
