Description
cos ( x + (3pi/2) ) = sin x
User generated content is uploaded by users for the purposes of learning and should be used following Studypool's honor code & terms of service.
Explanation & Answer
Please note that if I apply the formula of subtraction of the cosine function, I get:
left side = cos (x +3pi/2) = cos x cos (3pi/2) - sin x sin(3pi/2) = cos x * 0 - sin x * (-1) = sin x = right side,
since cos(3pi/2) = 0, and sin(3pi/2) = -1

T test analysis computation, computer science homework help
For this assessment, you will complete an SPSS data analysis report using t-test output for assigned variables.You will review the theory, logic, and application of t-tests. The t-test is a basic inferential statistic often reported in psychological research. You will discover that t-tests, as well as analysis of variance (ANOVA), compare group means on some quantitative outcome variable.By successfully completing this assessment, you will demonstrate your proficiency in the following course competencies and assessment criteria:Analyze the computation, application, strengths and limitations of various statistical tests.Develop a conclusion that includes strengths and limitations of an independent samples t-test.Analyze the decision-making process of data analysis.Analyze the assumptions of the independent samples t-test.Apply knowledge of hypothesis testing.Develop a research question, null hypothesis, alternative hypothesis, and alpha level.Interpret the results of statistical analyses.Interpret the output of the independent samples t-test.Apply a statistical program's procedure to data.Apply the appropriate SPSS procedures to check assumptions and calculate the independent samples t-test to generate relevant output.Apply the results of statistical analyses to a field of interest or career.Develop a context for the data set, including a definition of required variables and scales of measurement.Communicate in a manner that is scholarly, professional, and consistent with the expectations for members in the identified field of study.Communicate in a manner that is scholarly, professional, and consistent with the expectations for members in the identified field of study.Read the Assessment 3 Context document for important information on the following topics:Logic of the t-test.Assumptions of the t-test.Hypothesis testing for a t-test.Effect size for a t-test.Testing assumptions: The Shapiro-Wilk test and Levene's test.Proper reporting of the independent samples t-test.t, degrees of freedom, and t value.Probability value.Effect size.As you prepare to complete this assessment, you may want to think about other related issues to deepen your understanding or broaden your viewpoint. You are encouraged to consider the questions below and discuss them with a fellow learner, a work associate, an interested friend, or a member of your professional community. Note that these questions are for your own development and exploration and do not need to be completed or submitted as part of your assessment.VARIOUS FORMS OF THET-TESTIn what research situations should the paired samples t-test be used rather than the independent samples t-test?TWO VERSIONS OF THE INDEPENDENT SAMPLEST-TESTWhy are there are two different versions of the t-test on the SPSS printout and how you decide which one is more appropriate?APPLICATION OFT-TESTSIs there a research question from your professional life or career specialization that can be addressed by an independent samples t-test?Why would a t-test be the appropriate analysis for this research question?What are the variables and their scale of measurement?What is the expected outcome? (For example, "The group 1 mean score will be significantly greater than the group 2 mean score because…").REQUIRED RESOURCESThe following resources are required to complete the assessment.Assessment 3 Context.DAA Template.SPSS Data Analysis Report Guidelines.IBM SPSS Step-By-Step Instructions:t-Tests.Copy/Export Output Instructions.In addition, you will need the grades.savfile that you created from the grades2.datfile in Assessment 1.SPSS SoftwareThe following statistical analysis software is required to complete your assessments in this course:IBM SPSS Statistics (recent version for PC or Mac).This course requires the following as a minimum:IBM SPSS Statistics Standard GradPack. (The Base GradPack is not acceptable for use in this course.)Versioning:This software is routinely updated. While it is recommended that you use the latest version of the software, you may use an older version if you already own it or have access to it, but it mustbe version 22 or higher. Be sure to use the version that is compatible with your operating system (PC or Mac).SUGGESTED RESOURCESThe resources provided here are optional. You may use other resources of your choice to prepare for this assessment; however, you will need to ensure that they are appropriate, credible, and valid.

Deliverable 6 - Analysis with Correlation and Regression
CompetencyDetermine and interpret the linear correlation coefficient, and use linear regression to find a best fit line for a scatter plot of the data and make predictions.ScenarioAccording to the U.S. Geological Survey (USGS), the probability of a magnitude 6.7 or greater earthquake in the Greater Bay Area is 63%, about 2 out of 3, in the next 30 years. In April 2008, scientists and engineers released a new earthquake forecast for the State of California called the Uniform California Earthquake Rupture Forecast (UCERF).As a junior analyst at the USGS, you are tasked to determine whether there is sufficient evidence to support the claim of a linear correlation between the magnitudes and depths from the earthquakes. Your deliverables will be a PowerPoint presentation you will create summarizing your findings and an excel document to show your work.Concept being StudiedCorrelation and regressionCreating scatterplotsConstructing and interpreting a Hypothesis Test for Correlation using r as the test statisticYou are given a spreadsheet that contains the following information:Magnitude measured on the Richter scaleDepth in kmUsing the spreadsheet, you will answer the problems below in a PowerPoint presentation.What to SubmitThe PowerPoint presentation should answer and explain the following questions based on the spreadsheet provided above.Slide 1: Title slideSlide 2: Introduce your scenario and data set including the variables provided.Slide 3: Construct a scatterplot of the two variables provided in the spreadsheet.

Explain.Slide 6: Find the regression equation. Let the predictor (x) variable be the magnitude. Identify the slope and the y-intercept within your regression equation.Slide 7: Is the equation a good model? Explain. What would be the best predicted depth of an earthquake with a magnitude of 2.0? Include the correct units.Slide 8: Conclude by recapping your ideas by summarizing the information presented in context of the scenario.Along with your PowerPoint presentation, you should include your Excel document which shows all calculations.
