Question

Find the critical values for a 95% confidence interval using the chi-square distribution with 15 degrees of freedom. Round the answers to three decimal places.

Answer #1

Find the critical values for a 90% confidence interval assuming
this is a chi-squared distribution problem and the degrees of
freedom are 10.

Use the given information to find the number of degrees of?
freedom, the critical values chi Subscript Upper L Superscript 2
and chi Subscript Upper R Superscript 2?, and the confidence
interval estimate of sigma. 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?%
