Use
the given information to find the number of degrees of freedom, the
critical values x2/l and x2/r, and the confidence interval estimate
of the population standard deviation. It is reasonable to assume
that a simple random sample has been selected from a population
with a normal distribution.
Nicotine in menthol cigarettes 99% confidence; n=20, s=0.28
mg.

Expert Solution
Degree of freedom = n-1 = 20-1 = 19
Crtical values calculated using R software
Confidence interval is calculated using Minitab.
CI = (0.196 , 0.467 )
