In a study of copper deficiency in cattle, the cattle values both determined for cattle grazing in an area known to have well-defined molybdenum anomalies and for cattle grazing in a nonanomalous area ("An investigation into Copper Deficiency in Cattle in the Southern Pennines, "J. Agricultural Soc. Cambridge, 1972: 157-163), resulting in s1 = 21.5 (n1 = 48) for the anomalous condition and s2 = 19.45 (n2 = 45) for the nonanomalous condition, Test for the equality versus inequality of population variances at significance level 0.10 by using P-value approach.
