Use the given information to find the number of degrees of freedom, the critical values x² and X, and the confidence interval estimate of σ. It is reasonable to assume that a simple random sample has been selected from a population with a normal distribution. Nicotine in menthol cigarettes 80% confidence; n = 20, s = 0.23 mg.
