Question
Use the given information to find the number of degrees of freedom, the critical values x? and x, and the confidence interval estimate of o. 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= 27, s = 0.23 mg. Click the icon to view the table of Chi-Square critical values. df = I(Type a whole number.) (Round to three decimal places as needed.) (Round to three decimal places as needed.) mg. The confidence interval estimate of o is mg <o< (Round to two decimal places as needed.)
