In a study of copper deficiency in cattle, the copper values

(g Cu/100 mL blood) were determined both for cattle grazing in an area known to have well-defined molybdenum anomalies (metal values in excess of the normal range of regional variation) 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 (m
48) for the anomalous condition and s2
19.45 (n
45) for the nonanomalous condition. Test for the equality versus inequality of population variances at significance level .10 by using the P-value approach.
