HCS/438 DQ’s Week 1: DQ1: What are the differences between descriptive and inferential statistics? According to Bennett (2009)‚ the biggest difference between descriptive and inferential statistics is that descriptive statistics "deals with describing raw data in the form of graphics and sample of statistics" and inferential statistics "deals with estimating population parameters from sample data." This means that inferential statistics would be an estimate because the data would be estimated

The results for nitrate were inconclusive‚ there are traces of nitrate in wells 15‚ 20‚ 23‚ and 21 but we couldn’t find the source. We believe that number 15 is the source but there is very little amount of pollutants in the water to make the solution turn black. Wells 15‚ 20‚ 23‚ and 21 when tested for nitrates‚ the iodine changed to a yellowish blackish color. The hypothesis was not supported‚ well number 26 did not test positive for any of the pollutants. The first well tested was well number

RESULTS AND DISCUSSION In the Iron (II) - Silver Ions System the reaction had a balance chemical equation of Fe2+ + Ag+ Fe3+ + Ag(S). The process if centrifugation is used in this part of the experiment to be able to separate the supernatant and the precipitate. And the supernatant will be used to test for the presence of Fe2+‚ Ag+ and Fe3+ in the solution. Results showed that there is a positive presence for FE 2+‚ Fe3+ and Ag+ because of the visible change of color of Prussian blue precipitate

Results In this experiment we used paper chromatography to determine the amount of chlorophyll a‚ chlorophyll b‚ xanthophyll‚ and beta-carotene in a tube of blended leaf extract. We recorded our findings on the table labeled table 1. Table 1 shows the transmittance at each wavelength on a table from 400 to 720. The information on Figure 1 came from the leaf extract on the paper chromatography that we used; with the help of acetone we saw the spectrum and the differences of the different pigments

The mass of Gliese 581 is 30 percent of the mass of the sun. Luminosity means how bright something is‚ and the luminosity of Gliese 581 is .2 percent of the Sun’s luminosity. From this information‚ we know that Gliese 581 is a very dim star! There are three confirmed and two other possible planets that orbit Gliese 581. Each of these five planets are close to the star and have a circular orbit. The planets orbiting Gliese 581 were named in the order they were discovered and are named Gliese e‚ Gliese
