After collecting records on 17 individuals over 8 years, thepsychologist compiles the information listed in the table below. Conduct a linear regression to analyze theresearch question.The steps will be the same as theones you have been practicing in Part 1 of the assignment—the only differenceis that you are now responsible for creating the data file as well. Remember toname and define your variables under the “Variable View,” then return to the“Data View” to enter the data.

Constructa scatterplot of the relationship between the 2 variables. Plot the regressionline on this graph. (3 pts)3. Istime spent in after-school programs predictive of the number of arrests as ayoung adult? Write a Results section in current APA style describing theoutcome. All homework “Results sections” must follow the example given in theCourse Content document “Writing Results of Statistical Tests in Current APAFormat” (Note: you do not have to refer to a figure). The statistical statement for a bivariate linear regression mustinclude at least the equation of the line and the confidence interval for theslope (the second row under Confidence Intervals in the output).
