Probability density function

Lab 4 in Chem 115 has three parts all calculating density. In part one, a 100 mL beaker, a volumetric pipet, and an analytical scale were obtained. To begin, the mass of the beaker was taken using an analytical scale. Then, 10.0 mL of an unknown liquid was transfered to the beaker using the volumetric pipet. Next, the mass of the beaker and liqiud was recorded along with the letter identifying the unknown liquid. By subtracting the mass of the 100 mL beaker from the mass of the beaker and liquid…

In this experiment the students were required to provide urine samples three times in 60 minutes. This experiment was done to test urine volume, flow rate, total dissolved solids, and pH at each interval and record the differences in these variables depending on what each participant was asked to eat or drink. I hypothesized that the subjects asked to eat pretzels and drink soda would see an increase in total dissolved solids in their urine. In this experiment the 20 test subjects had to provide…

Data Calculated from Experiment Solid-Liquid Weight (g) Solid-Liquid % Recovery Liquid-Liquid Weight (g) Liquid-Liquid % Recovery Acid 0.01 20 % 0.028 56 % Phenol 0.011 22 % 0.001 2 % Amine 0.013 26 % 0.005 10 % Neutral 0.03 60 % 0.026 52 % Table 1 shows the data obtained from this experiment of both the solid-liquid extraction (on the left side of the table) and the liquid-liquid extraction method (on the right side of the table). It shows that in the solid-liquid extraction, most of the…

In definition, probability refers to the measure of the likelihood of an event happening. The probability for any event occurring falls between 1 percent and 100 percent thus meaning that the interpreted meaning of a probability equals the subject meaning held of the probability (Grinstead et al, 1997). However, it is worth noting that the application of probability or assigning of probability to the events in the effort to gratifying the axioms of probability follows some rules or basics…

conditional probability representation. In additional, truth tables and probability are today uses. Bayes Theorem is the final concept in statistics, which is defined as the description of the probability of events based on related conditions. Thomas Bayes developed P (A|B) = P (B|A) (P (A) / P (B) where Pierre-Simon Laplace further the Bayes theorem formula and Sir Harold Jeffreys defined the Bayes Theorem as the theory probability. There are no early uses and is used for probability, odds,…

Uncertainty in Economics and Other Reflections (1955) by G.L.S. Shackle (Cambridge: University Press). The book is divided into eighteen sections written between 1939 and 1953, each of which consists of a journal article. Among these sections, nine refer to the notions of expectation and uncertainty – main points of concentration of the present critical review – two are focused on interest rate, four on investment and unemployment, and the three remaining ones on a philosophy of economics.…

Probability concepts like faith, as it exists in the dim intuition, through school education, the surface of that understanding, intuition often conflicts that again with a different point of view, must be thinking more in-depth study to be able to understand. Hot Monty Hall problem, and that is one example. There is not a simple probability, long confused with so many people and academics, the more deeply ponder the problems found. Since 1990, 1991 flared up in hot to 2000, there are more…

AIM OF THE PRACTICAL The aim of this practical was to investigate the reality or the accuracy of the formula for the resultant force on and the position of the centre of pressure on a vertical rectangular surface. SKETCH OF APPARATUS Counterbalance weight Balance pan(with 20g mass piece) Flat/curved surface(as shown below) Water Beaker Mass pieces(20g each) SUMMARY OF THEORY Hydrostatic force is the force exerted by the…

to push it up causing it to float; the less density of the boat the nearer to the surface the vessel floats. The boat…

three questions in regards to density. The first question inquired which method of density calculation would be the most accurate. The second question asked if the sugar in the soda had an effect on its density. The third question stated what affect the varying size and shape of the copper pieces had on their density. These questions were explored in the experiment and some interesting conclusions were made at the end. In the first half of the experiment, the density of copper is calculated…
