2.5. A sample of 15 g carbonated salt with density of 2650 kg/m3 is poured into a liter of water to form a suspension. The prepared suspensionwas used to fill up an Andreasen Pipette vessel to the 20 cm mark. Suspension samplesweretaken at:2,8, 16,32, 60,120, 180, 240, 360, 480, 600, and 1440 min. The weight concentrations on10 mL of the every extracted samplewere:0.1465,0.0967,0.0883, 0.0632, 0.0386,0.0294, 0.0178,0.0104, 0.0073,0.0051,0.0030, and 0.0008 g. If every extracted sample drops the height level inthe vessel 0.5 cm, evaluate the median size of the carbonated salt particles.

You have been hired to measure the concentration of ammonia in water from wells at two districts on Long Island. After sampling 10 wells in one of the districts you find the values are, in mg/L: 6.4, 2.1, 1.4, 0.7, 6.8, 3.2, 2.7, 1.6, 4.9, 1.2. Your assistant plots the data from the second set of wells and the histogram of data from that sample looks pretty much the same as for your data set. Which statistical test do you anticipate that you will use? An one-sample t-test An unpaired, two-sample t-test A paired, two-sample t-test A one-way anova A Mann-Whitney U test Main Content
