bivariate linear regression problem

I need help with an APA results section on a bivariate linear regression problem. 

PSYC 355 SPSS H OMEWORK 6 I NSTRUCTIONS P REDICTION - B IVARIATE L INEAR R EGRESSION Part 1: Note: You will use raw data for all homework exercises with no need to convert to z scores. Green & Salkind: Lesson 33 Exercise Open Lesson 33 Exercise File 1 found in Blackboard Course content (under Syllabus and Assignment Instructions—Assignment Instructions—SPSS Homework 6—SPSS Homework 6 Files—Mod6_Lesson 33 Exercise File 1). This data set pertains to Peter’s study on the number of times boys hit a doll and a peer, as described in the end of chapter exercise in Green and Salkind Lesson 33. Read the research scenario in the text, then follow the directions below as some questions have been altered. 1. Conduct a linear regression to predict the number of times a boy would strike a classmate from the number of times the boy hit a bobo doll. Use raw scores, not z scores, in the regression analysis. Paste SPSS output, then answer the following questions: Descriptive Statistics Mean Std. Deviation N Number of times hitting a peer 11.60 20.095 10 Number of times hitting a bobo doll 4.90 8.048 10 Correlations Number of times hitting a peer Number of times hitting a bobo doll Pearson Correlation Number of times hitting a peer 1.000 .930 Number of times hitting a bobo doll .930 1.000 Sig. (1-tailed) Number of times hitting a peer . .000 Number of times hitting a bobo doll .000 . Page 1 of 9
