# Write a 2- to 3-paragraph analysis of your correlation and bivariate regression results for each research question

Write a 2- to 3-paragraph analysis of your correlation and bivariate regression results for each research question. Do not forget to evaluate if the correlation and bivariate regression assumptions are met and report the effect size. In your analysis, display the data for the output. Based on your results, provide an explanation of what the implications of social change might be.

Sketch a sample Riemann rectangular slice in R to guide your solution process . Then, set up the integral to determine the area of that region. Finally, evaluate the integral to determine the area of the region. 3) Use the general slicing method to find the volume of the following solid. The solid whose base is the region bounded by the curve s = 2 and = 2 − 2, and whose cross -sections through the solid perpendicular to the x -axis are squares. 4) Use the washer method to determine the volume of the object described below . Determine the volume of the object created by rotating the region bounded by = 1, = √ cos () and the x-axis on the interval , about the x-axis . -p 2,p 2 é ëê ù ûú 5) Use the diagrams below to answer the following questions: 6) Explain why someone who memoriz es the washer and shell method formulas in the text should be extremely careful when solving problems of revolution. a) Suppose the bounded region in the graph to the right is rotated about the y-axis . Which integration method will require only one integral ? (Circle one) Washer Method Shell Method Draw in an appropriate rectangular slice in the diagram for the method you chose. b) Suppose the bounded region in the graph to the right is rotated about the x-axis . Which integration method will require only one integral ? (Circle one) Washer Method Shell Method Draw in an appropriate rectangular slice in the diagram for the method you chose. 7) Set up and evaluate an integral to find the volume of the solid obtained by rotating the given region bounded by = 2 and = 2 a) About the line = − 1, using the washer method ! b) About the line = − 1 using the shell method !    
