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 90% confidence; n=23, s=65.2.
Can you please simplify the solution so i can do the rest on my own.
Thank you!

Solution :
Given that,
s = 65.2
s2 = 4251.04
n = 23
df = 23 - 1= 22
2L
=

/2,df
= 33.924
2R
