Choose the correct answer
A cigarette manufacturer wishes to test the claim that the variance of
the nicotine content of its cigarettes is 0.644.
Nicotine content is measured in milligrams, and assume that it is
normally distributed. A sample of 20 cigarettes has
= 0.05,
a standard deviation of 1.00 mil- ligram. At a
is there the critical values =
the critical values are 26.4 and 18.7
the critical values are 42.852 and 28.907
the critical values are 64.236 and 12.367
None
