How do I run a regression on NDVI raster values?

Hello, I'm trying to wrap my head around a raster analysis concept. I have an NDVI map of my study area. On this map, I have point features for which I have created a small buffer around them, therefor creating a set of round polygons on the map that I use to measure NDVI values within. Each of these points or buffer areas corresponds to a different plant species. I have ran the zonal statistics to get the average NDVI means of each buffer area so I can get a rough idea of the mean NDVI values for which the species can be found. I now want to know if there is a statistically significant difference between the mean NDVI values of the plant species, i.e. are the values significantly different? I want to know if arcgis can give me p-values so I can reject or accept the null hypothesis (0.05 confidence) (species A has a different mean NDVI value than B, Species A has the same NDVI mean as species D, etc.)
