aking into account the type of comparison that you previously identified for this study, calculate a 95% confidence interval for he difference in cone mass between islands with and without squirrels. Assume that sites were randomly sampled. (Measure the ifference as islands without squirrels minus islands with squirrels.) Give your answer as an interval in the form (lower bound, upper bound). Round each bound to two decimal places. Use tatistical Table C if necessary.

Transcribed Image Text:The table presents mean cone size (mass) of lodgepole pine in 16 study sites in three types of environments in western North
America (Edelaar and Benkman 2006). The three environments were islands of lodgepole pines in which pine squirrels were
absent (an "island" here refers to a patch of lodgepole pine surrounded by other habitat and separated from the large tracts of
contiguous 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 islands
with and without squirrels, because this comparison controls for any effects of forest isolation on the mass of lodgepole
pine cones.

the difference in cone mass between islands with and without squirrels. Assume that sites were randomly sampled. (Measure the
difference as islands without squirrels minus islands with squirrels.)
