how does logging in a tropical rainforest affect the forest several years later? researchers compared forest plots in borneo that had never been logged (group 1) with similar plots that had been logged 11 year earlier (group 2) and 88 years earlier (group 3). although the study was not an experiment, the authors explained why the plots can be considered to be randomly selected. the anova output for the number of trees in forest plots in borneo is given, and the corresponding dotplots are provided. a. what observations can be made about the variation by looking at the dot plot b. state null and alternative hypothesis. c. what are the value of test statistics and p-value? d. state your conclusion in the context of the problem
