Four fabrics are tested for flammability at the National Bureau of Standards. Burn times (in seconds) are recorded after a paper tab is ignited on the hem of a dress made of each fabric. ## Load the data from our course website (HW06_FabricData.csv) into a data frame named *FabricData*. The burn times will be contained in the *BurnTime* variable of the data frame (FabricData\$BurnTime) and the conditions (i.e. fabric number) will be contained in the *Fabric* variable (FabricData\$Fabric).

Then post a comparison commenting on any similarities and differences you observe in the important characteristics (distribution, central tendency, and dispersion) between the student generated sample means and the original population (a uniform distribution with a mean of 3.5 and a standard deviation of 1.7) of data values contained on a standard six sided die.
