The two-way table below records all 2,050 trees in the plot by species and life stage. Sapling trees (young trees shorter than 1.3 meters) are indicative of the future of the forest. Test the relationship between species and life stage. - When calculating the Chi-square statistic, each cell of the table makes a contribution to the total. What contribution do western red cedar saplings make? (The sum of all contributions resulted in a Chi-square statistic of 420.21) Can you explain this with table of expected counts like dead, live, sapling of western red cedar/douglas fir/western hemlock?Hello, please answer as soon as possible.
