df= (Type a whole number.) χ2L= (Round to three decimal places as needed.) χ2R= (Round to three decimal places as needed.) The confidence interval estimate of σ is mg <σ< mg. (Round to two decimal places as needed.)
Use the given information to find the number of degrees of freedom, the critical values χ2L
and χ2R, and the confidence
Nicotine in menthol cigarettes 95%confidence; n=24, s=0.26 mg.
df= (Type a whole number.)
χ2L= (Round to three decimal places as needed.)
χ2R= (Round to three decimal places as needed.)
The confidence interval estimate of σ is mg <σ< mg.
(Round to two decimal places as needed.)
Given : n=24 , s=0.26 , α=0.05
Our aim is to find the
