ex0429

The data are the number of tree seedlings per transect in nine logged (L) and 
 seven unlogged (U) plots affected by the Oregon Biscuit Fire, in 2004 and 2005, 
 and the percentage of seedlings lost between 2004 and 2005. The goal is to see
 whether the distribution of seedlings lost differs in logged and unlogged plots.
