Determination of Unknown Block Material and Uncertainty Analysis Xuan Wang TA: Saurabh Chawdhary ME4031W Lab Section 014 4:40PM Wednesday 2/10/2013 Abstract People discovered many methods to determine the properties of unknown materials (harness, density, or elastic modulus etc.). In this lab, the task is to find the density of an unknown block. If the dimensions and mass of unknown block can be obtained, the density can be calculated by block mass over block volume. After comparing the result density value to a reference chart, the specific material category can be determined. Dimensions can be measured by using a caliper and a micrometer and mass can be determined by putting the block onto an electronic balance.
The level required is 4 shuttles at level 5 (5.4). You will run 44 shuttles to reach this level. You are likely to pass if you can run 1.5 miles in 12 minutes or run on a treadmill for 8 mph for 12 minutes at zero gradient. (2) Dynamic Strength Test (Push-Pull) This test is carried out on a Concept 2 DYNO machine. After 3 warm up pushes, you will then have to push as hard as you can 5 times.
Discuss how the Empirical Rule works and how it relates to the bell curve as illustrated in Figure 3.14 (a). Then, explain Chebyshevís Theorem and how it is different from the Empirical Rule. Give a specific example of a population with which the Empirical Rule might be most effective and one with which Chebyshevís Theorem might be most effective. Quiz 1. Due Day 6.
The preparation was allowed to equilibrate for five minutes. A coverslip was applied and the preparation observed in the microscope. The culture of Paramecium aurelia was mixed. A drop of culture was then placed on a glass slide with an equal volume of Protoslo. A coverslip was applied and the preparation observed in the microscope.
Experiment Research and The Scientific Method There is a place for accepting hypotheses based on the results of repetition in scientific research. This approach is referred to as the inductive method. Numerous observations should be made over a period of time. After the same cause-and-effect process is observed repeatedly, a hypothesis can be accepted as true inductively. No formal testable hypothesis was set up, but there is enough experiential evidence to accept that an outcome will predictably result from a specific action.
* We kept the foam block (metal in the box) at the end of the ramp. On the jack(an equipment which is used to vary heights), the top of the ramp was placed on it. * The Light gates detector was placed at the finishing point of the ramp. * Like in method 1, the five different heights : 0.10m, 0.15m, 0.20m, 0.25m and 0.30m were taken. * The final speed was recorded by the light gate detector about three times for each height.
Math 533 Course Project: AJ DAVIS DEPARTMENT STORES Project Part B: Hypothesis Testing and Confidence Intervals Summary Report In order to calculate the probability of each situation hypothesis tests were administered on each scenario. In summary, hypothesis testing is used to check whether there is or is not likely to be a difference between one or more data sets. In statistics there is no such thing as 100% sure so uncertainty must be allowed. Instead the best thing we can do in statistics is to show things are false to make the best inferences. The following information below describes what was concluded from the hypothesis tests below.

He is currently the Herman Feshbach Professor of Physics at the Massachusetts Institute of Technology. This quotation relates to the work we are doing in GS1145 in that it stresses the importance of taking hard problems and working through them - mistakes and all. By making mistakes we are able to learn from them and are really challenged to come up with core solutions. This includes working
By the adjacent student distracted by the wobbling legs of my table. Every person is able to verify every aspect of the objective world. As Democritus stated “Nothing exists except atoms and empty space, everything else is just opinion.” and if reality is defined as what actually exists, then the tangible is our only reality. And this is where the chaos begins… One may argue “How do you know the blue I see is the blue you see? How do you know that this book is real?
