Escherichia coli Microbiology Lab NAS 185-14L Introduction In this lab experiment we did several test to determine what our unknown bacteria was. To determine this we recorded the results of how the bacteria reacted to different media. Depending on the results of each test we could narrow down the different bacteria to determine what our unknown is. This experiment will also determine if our bacteria is a fermenter of sugars and if it is catalase positive. If the bacteria is a fermenter

Twenty- one. A guard of the Tomb of the Unknown Soldier takes twenty-one steps during his walk across. This number alludes to the twenty-one gun salute‚ the highest honor given any military of foreign dignitary. The guards hold their task in their highest regards. They look their ability to guard the Tomb of the Unknown in highest regards. Similarly‚ it would be an indescribable honor for me to be able to lay the wreath upon the Tomb. Three reasons why it would be such an honor to be able to

Chapter 8: Hypothesis Testing: 8.1 Review and Preview: The two main activities of inferential statistics are using sample data to (1) estimate a population parameter (such as estimating a population parameter with a confidence interval)‚ and (2) test a hypothesis or claim about a population parameter. Hypothesis: a claim or statement about a property of a population Hypothesis test/test of significance: a procedure for testing a claim about a property of a population Population proportion

A hypothesis is a tentative statement predicting a particular relationship between two or more variables. If you want to know whether or not your study requires a hypothesis‚ ask yourself these questions: Are you undertaking a quantitative study? Does your study take an experimental approach to answer questions? Are you making a prediction about the phenomenon being studied? If your answer to these questions is ’yes’‚ then you will need a hypothesis‚ but if it is ’no’ then you will need a

Purpose: I will identify an unknown liquid by obtaining an average density & boiling point for my liquid and comparing them with the known densities & boiling points of liquids in the CRC handbook of Chemistry & Physics. I will perform these experiments using three different measuring tools (graduated cylinder‚ burette & pipette) to evaluate the precision of each one. Results: Density 1‚ 2 & 3 calculated by using graduated cylinder to obtain volume. Density 4‚ 5 & 6 calculated by using volumetric
