please answer the question - answer is not The table presents mean cone size (mass) of lodgepole pine in 16 study sites in three types of environments in western NorthAmerica (Edelaar and Benkman 2006). The three environments were islands of lodgepole pines in which pine squirrels wereabsent (an "island" here refers to a patch of lodgepole pine surrounded by other habitat and separated from the large tracts ofcontiguous lodgepole pine forests), islands with squirrels present, and sites within the large areas of extensive lodgepole pines("mainland") that all have squirrels.The main comparison of interest in this study, identified before the data were gathered, was the comparison between islandswith and without squirrels, because this comparison controls for any effects of forest isolation on the mass of lodgepolepine cones.Habitat typeIsland, squirrels absentIsland, squirrels presentMainland, squirrels presentClick to download the data in your preferred format.CSV Excel JMP Mac-Text Minitab PC-Text R SPSS TI CrunchIt!Raw data (g)9.6, 9.4, 8.9, 8.8, 8.5, 8.26.8, 6.6, 6.0, 5.7, 5.36.7, 6.4, 6.2, 5.7, 5.6Mean SD8.90 0.536.08 0.626.12 0.47Taking into account the type of comparison that you previously identified for this study, calculate a 95% confidence interval forthe difference in cone mass between islands with and without squirrels.
