Discussion: Multiple RegressionAs with the previous week’s Discussion, this Discussion assists in solidifying your understanding of statistical testing by engaging in some data analysis. This week you will once again work with a real, secondary dataset to construct a research question, estimate a multiple regression model, and interpret the results.Whether in a scholarly or practitioner setting, good research and data analysis should have the benefit of peer feedback. For this Discussion, you will post your response to the hypothesis test, along with the results. Be sure and remember that the goal is to obtain constructive feedback to improve the research and its interpretation, so please view this as an opportunity to learn from one another.To prepare for this Discussion:Review this week’s Learning Resources and media program related to multiple regression.Create a research question using the General Social Survey that can be answered by multiple regression.By Day 3Use SPSS to answer the research question. Post your response to the following:What is your research question?What is the null hypothesis for your question?What research design would align with this question?What dependent variable was used and how is it measured?What independent variable is used and how is it measured?What other variables were added to the multiple regression models as controls?What is the justification for adding the variables?If you found significance, what is the strength of the effect?Explain your results for a lay audience, explain what the answer to your research question.Be sure to support your Main Post and Response Post with reference to the week’s Learning Resources and other scholarly evidence in APA Style.

Directions: Solve each of the following problems.Find the exact value of:1. Cos 200 cos 45 0 + sin 20 0 sin 4502. Cos 520 cos 320 - sin 520 sin 3203. Sin 220 cos 380 + Cos 220 sin 3804. Sin 850 cos 200 - Cos 850 sin 2005. Cos 120 cos 100 - sin 120 sin 1006. If sinx = 5/6, find Cos (2x)7. If sinx = 7/9, find Cos (2x)8. If sinx = 2/8, find Cos (3x)9. If sinx = 4/8, find Cos (6x)10. If sinx = 2/8, find Cos (1x)
