Statistics Assignment 9 (additional pages+payment) - Speech or Presentation ExampleOften, the investigate is carried out as a double blind test where both the doctors and patients do not tell apart whether the given dose is actually a placebo or not. A simplified approach to this type of audition may result in the table seen below.From this table, the problem can actually be handled as a chi square problem. Specifically, the rivulet of Homogeneity may be used in such a case. In such a case, the null hypothesis is that the ratio of nucleusive against non-effective cases for both the impudently drug and the placebo must be equal. If the drug is to be considered for use, there must be a high opportunity of rejecting the null hypothesis hence indicating a significant difference between the control group (placebo group) and the tally group.In contrast, the lack of a control group would simply result to a measure of whether the new drug was effective or not. Since the testers are bound to think that the new drug would cure their complaints, the placebo effect takes place and the results of the experiment will no longer be reliable.The chi square approach establishes a framework for testing with non-parametric probability distributions. That is, the distribution is not defined by parameters such as the recollect and standard deviation in the case of the normal distribution. Instead, the frequency or probabilities of certain observations are needful to describe a model. Three applications of the chi square paradigm are the uprightness of Fit, Test of Independence, and Test of Homogeneity. While the three revolve around the same approach, they differ slightly in terms of interpretation.The Goodness of Fit testing approach is used when the expected probability of certain observations are known. This test compares the actual observations from the expected values and determines whether there is a significant deviation from the expected probabilities. An exampl e for this would be a die roll. Each side of the die is supposed to appear as often as
