An article in Biological Trace Element Research [Interaction of Dietary Calcium, Manganese, and Manganese Source (Mn Oxide

An article in Biological Trace Element Research [€œInteraction of Dietary Calcium, Manganese, and Manganese Source (Mn Oxide or Mn Methionine Complex) or Chick Performance and Manganese Utilization€ (1991, Vol. 29(3), pp. 217€“228)] showed the following results of tissue assay for liver manganese (ppm) in chicks fed high Ca diets.

(a) Test the hypothesis H₀: σ² = 0.6 versus H₁: σ² ‰  0.6 using α = 0.01.

(b) What is the P-value for this test?

(c) Discuss how part (a) could be answered by constructing a 99% two-sided confidence interval for σ.
