NettetFor all coniferous sites, there was a strong linear correlation between the SA plot and the LA plot, and the p-value supports that the correlation is not zero. However, if a regression model was derived by using both sample sets (10 × 10 m and 60 × 60 m stands), the lack-of-fit test is significant at a p -value of 0.019. NettetH 0: ρ = 0. H a: ρ ≠ 0. α = 0.05. The p-value is 0.026 (from LinRegTTest on your calculator or from computer software).; The p-value, 0.026, is less than the significance level of α …
