The difference and if it is significant or not is an important aspect of research. this could be done by performing many different tests. Do you know what we would run to find out the variance?Part 3Write a 250- to 300-word response to the following:How do you choose which measure of variation to use and what considerations may have an impact on your decision?Use at least 1 scholarly source.Part 4Respond in 150-200 wordsThe type of research and the data being analyzed will affect the appropriate measure. Do you think they could be interchanged, or do you think the wrong measure would screw up a study?

Formulate and evaluate hypothesis tests for population parameters based on sample statistics using both Critical Regions and P-Values, and be able to state results in a non-technical way that can be understood by consumers of the data instead of statisticians.Student ProfileYou are a statistician working for a drug company. A few new scientists have been hired by your company. They are experts in pharmacology, but are not experts in doing statistical studies, so you will explain to them how statistical studies are done when testing two samples for the effectiveness of a new drug. The two samples can be dependent or independent, and you will explain the difference.Concept being StudiedYour focus is on hypothesis tests and confidence intervals for two populations using two samples, some of which are independent and some of which are dependent. These concepts are an extension of hypothesis testing and confidence intervals which use statistics from one sample to make conclusions about population parameters.What to SubmitYour research and analysis should be presented on the Word document (attached) provided. All calculations should be provided on a separate Excel workbook (you must provide yourself) that should be submitted to your boss as well.YOU MUST MEET THE BELOW REQUIREMENTS: All problems are solved correctly. Complete and detailed steps are provided to explain how to solve the problem. Explanations demonstrate a mastery of understanding of the statistical concepts and terminology. All variables, equations, and expressions are properly formatted.
