Quantitative Techniques Lab 5 (Topic 3: Hypothesis Testing) ------------------------------------------------- Procedure for Hypothesis Testing Step 1: Formulate the null and alternative hypothesis. Draw the one-tail or two- tail test diagram. Step 2: Specify the level of significance. Determine the critical value (s). Step 3: Identify the test statistics to be used and calculate it. Step 4: Draw the conclusion. Formulae List Hypothesis Testing Test Statistics for Single Mean

Hypothesis testing begins with the assumption that randomization is used to collect quantitative data about the sample and that the distribution of this data has a normal shape. Significance tests state two explanations‚ or hypotheses‚ about a parameter. One‚ called the null hypothesis‚ states that the parameter equals some value (usually 0). The other‚ called the alternative hypothesis‚ states that the parameter is greater than‚ less than or (not) equal to the value stated in the null hypothesis

Efficient Propeller Design | AbstractHow does a helicopter generate enough lift to fly? How does a speedboat get moving fast enough to pull someone on water skis? Here ’s a project on designing propellers to do the job. ObjectiveThe goal of this project is to investigate how changes in chord length affect the efficiency of propellers.IntroductionA propeller‚ like an airplane wing‚ is an airfoil: a curved surface that can generate lift when air moves over it. When air moves over the surface of

This paper describes the origins of biomolecules hypothesis. Each different hypothesis is derived from a different scientist. It explains their claim and answers the question if the origin of biomolecules using their hypothesis. All the scientists provided evidence to help support their hypothesis. Some of the scientists had experiments to test their hypothesis. They also gave reasoning for supporting their theory. The Primordial Soup Hypothesis was introduced by the Soviet biologist Alexander

Solar Nebular Hypothesis The idea behind the Solar Nebular Hypothesis is that the solar system was condensed from an enormous cloud of hydrogen‚ helium‚ and a few other elements and rocks. Around five billion years this cloud of materials began to spin and contract together into a disk shape under their own gravitational forces. The particles started combined together‚ protoplanets‚ to eventually form planets. A great mass of the material eventually began to form together‚ protosun‚ and make

In the Harvard Business Review article "Market Lunacy‚" Lisa Burrell describes how researchers Ilia Dichev and Troy Janes asked the question whether the common belief that the moon changes moods and causes depression may actually be accurate or is it a myth. They believe that most studies have focused on extreme cases so they decided to focus on stock exchanges with the assumption that something that involves millions of people around the world participating in it every day should indicate any deviation

dopamine hypothesis of schizophrenia was first proposed more than 30 years ago on the basis of indirect evidence (776-786). The hypothesis happened to be a hit so It received support from studies of postmortem brain tissue that found increased striatal D2/3 receptor density and dopamine levels in patients with schizophrenia and from studies of dopamine and its metabolites in cerebrospinal fluid (776-786). Even though the studies of postmortem brain tissues supported the dopamine hypothesis of schizophrenia
