Use the One-Standard-Deviation Chi-Square Interval Procedure to Obtain the Specified $\sigma$

Multiple Choice

Use the one-standard-deviation chi-square interval procedure to obtain the specified confidence interval for the population standard deviation $\sigma$ . Assume that the population has a normal distribution.
-The weights of 22 randomly selected eggs have a mean, $\bar { x }$ , of $1.56 \mathrm { oz }$ and a standard deviation, s, of $0.49$ oz. Determine a $95 \%$ confidence interval for the standard deviation, $\sigma$ , of the weights of all such eggs.

A) $0.38$ to $0.70 \mathrm { oz }$
B) $0.39$ to $0.64 \mathrm { oz }$
C) $0.37$ to $0.68 \mathrm { oz }$
D) $0.39$ to $0.66 \mathrm { oz }$
