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.
Platelet Counts of Women 99​% ​confidence; nequals23​, sequals65.1.

Answer #1

Refer chi-square table or use excel formula "=CHISQ.INV.RT(0.995,22)" & "=CHISQ.INV.RT(0.005,22)" to find the critical values.
