Hypothesis tests are frequently used to measure the quality of sample parameters or to test whether estimates on a given parameter are equal for two samples. Hypothesis tests are parametric tests when they assume the population follows some specific distribution (such as normal) with a set of parameters. The t-test determines whether a sample is representative of a known population or whether paired samples are likely to be from the same. This test is used for descriptive test in sensory science.

As a result of the tests ran‚ I was able to identify the unknown bacteria. For Unknown A‚ I ran six tests. I first isolated the bacterium from the second bacterium and found a clear growth (Table 1‚ Figure 1). Secondly‚ I ran a gram stain and found a gram positive‚ cocci bacterium (Table 1‚ Figure 2). Third‚ I ran a catalase test in which was negative (Table 1). From here‚ I determined a starch hydrolysis test would be necessary to distinguish between different bacteria. The result was negative (Table

1. Both of the subjects in this test preformed excellent compared to the rankings provided. Victors Mean Power put him in between the 85 to 90 percentile with his score of 639.83 and his Anaerobic Capacity put him in between the 60 to 65 percentile. These scores indicate that Victor trains more with resistance than aerobic type exercises because of the high score of his Mean Power. These scores also correlate with his VO2 Max test we preformed earlier. His VO2 Max of 3.4 is low compared to the high

4 gram stains‚ the slide was blot dried and observed under microscope at 100x with oil immersion. The slide either appear in pink (gram-negative) or purple (gram-positive). Catalase Test: Catalase test enzyme detection of microorganisms‚ catalase hydrolysis hydrogen peroxide (H2O2) into H2O and O2. The catalase test was performed by used a sterile transfer loop been flamed to remove small amount of bacteria from slant agar and placed on the slide. Then

Enzyme Activity Lab Objective: To determine the effect of temperature‚ PH and enzyme concentration on catalase activity. Introduction: What is an enzyme and how the enzyme works. Any of a group of complex proteins or conjugated proteins thatare produced by living cells and act as catalysts in specific biochemical reactions. The system in which enzymes work is often referred to as the ’lock and key’ system it’s where the enzyme and the substrate lock together. The substrate then unlocks into

1. Introduction The Jominy end-quench test is a technique that has the ability to harden the steel by quenching. It is an essential feature of materials that determine the material’s selection for particular applications. The different types of steels and alloys that are used for hardening in an industry are done by this test and considering that this test is a standardised experiment [1]. 1.1 Aim The specimens that are used in this test are normalized in accordance with the standards. The purpose

Science Exit Project: Weather Weather itself is the state of the atmosphere at a given time. The weather seems very difficult to predict‚ however it is not as complicated as it seems. After looking at the variables and breaking down the pattern‚ a prediction can be made of the weather. The goal of this experiment is to look at the weather conditions for a given month‚ and then tell what shaped it‚ or what caused a certain variable to change. Procedure/Materials: First‚ I made a chart of the weather

no need for distillation. Next‚ a solubility test was given. When one drop of the unknown liquid was added to about 2 mL of water‚ the sample was tested to be soluble due to the dissolubility between the two compounds. By following the chart that was given on the sheet‚ the pH of the solution was tested. Since the two litmus did not changed color‚ the sample was identify to have a low molecular weight and a neutral substance. Based on the solubility test‚ some possible
