2. A biologist is interested in understanding how wildfire affects the diversity of flowering plants in the understory of longleaf pine in the southeastern US. The biologist randomly selected 14 sites in different longleaf pine forests and established 1 acre plots at each site. During the Spring, the biologist measured the number of flowering plant species in each plot as a measure of diversity. The following Fall, the biologist and the research team set prescribed fires to burn the understory vegetation in each plot. Then the biologist measured flowering plant diversity in the plots the next Spring. The resulting data are shown below. The result of all shapiro-.. - tests for these data were p
