Use the given information to find the number of degrees of freedom, the critical values χ2L and χ2R, 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 95% confidence; n=22, s=0.26 mg. df= (type a whole number) X2/L= (round to three decimal places as needed) X2/R= (round to three decimal places as needed) The confidence interval estimate of σ is __ mg < σ < __ mg. (round to two decimal places as needed)
