95% confidence interval of Y = Y ± t10°.°5^ w)-1/2 = 0.3018 ± 2.228X 0.09333 = 0.5097 and 0.09386, for 10 df, t10 = 2.228. Antilog Y = X = combined estimates of x = antiloge(0.3018) = 1.3623.

Equivalent X values = antilog (0.5097) = 1.6638 and antilog (0.09386) = 1.0984.

Significance of the difference of X from unity = X2 = ^ = 10.4554 (p<0.01).

Heterogeneity expression X2n_l = Pwy2 - ( ^Wy) = 9.4603 (p<0.10), = 10 df.
