In a field experiment designed to investigate the role of genetic diversity in ecosystems, Reusch et al. (2005) planted eelgrass in plots in a shallow estuary in the Baltic Sea. Eighteen eelgrass shoots were planted in every plot. Some plots (randomly chosen) were planted with only one eelgrass genotype, others were planted with three genotypes, and others were planted with six different eelgrass genotypes. At the end of the experiment, the total number of shoots was counted in each plot. The results from 32 plots are given in the following table: #genotypes 1 3 6 # shoots 11, 14, 21, 27, 28, 30, 32, 32, 36, 38, 49, 61, 71 obs freq = treatment 20, 35, 36, 41, 46, 47, 52, 53, 58, 67 31, 45, 45, 47, 48, 62, 64, 69, 84, 86 What is the appropriate null hypothesis for this analysis? exp freq, the shoot number will be similar by genotype var among s variance within, the shoot number will be similar by genotype treatment Or = 0, there is no association between shoot number and genotype treatment b = 0, there is no relationship between shoot number and genotype
