Question
**Exercise: Constructing a Confidence Interval for Population Standard Deviation** Buck randomly selects 38 basketball shoes from the Shoe Warehouse and finds the mean price to be $66.88 with a standard deviation of $5.62. Construct a 99% confidence interval for the population standard deviation σ, and find the χ² values used in the calculation. **Options:** A. $(4.31, 7.93)$ with χ²ₗ = 18.586 and χ²ᵣ = 62.833 B. $(4.27, 7.78)$ with χ²ₗ = 19.286 and χ²ᵣ = 64.181 C. $(1.82, 3.34)$ with χ²ₗ = 18.586 and χ²ᵣ = 62.833 D. $(4.27, 7.78)$ with χ²ₗ = 19.960 and χ²ᵣ = 59.893 E. $(18.58, 62.88)$ with χ²ₗ = 18.586 and χ²ᵣ = 62.833
