question 75

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 \(0.66 \mathrm { oz }\)
