need help with z-scoring method work

1.  A
community psychologist is interested in whether spending time in after-school
programs is predictive of the number of arrests as a young adult in a high-risk
neighborhood. After collecting records on 17 individuals over 8 years, the
psychologist compiles the information listed in the table below. Conduct a linear regression to analyze the
research question.

The steps will be the same as the
ones you have been practicing in Part 1 of the assignment—the only difference
is that you are now responsible for creating the data file as well. Remember to
name and define your variables under the “Variable View,” then return to the
“Data View” to enter the data. (3 pts)

Table is shown
on the following page.

2.  Construct
a scatterplot of the relationship between the 2 variables. Plot the regression
line on this graph. (3 pts)

3.  Is
time spent in after-school programs predictive of the number of arrests as a
young adult? Write a Results section in current APA style describing the
outcome. All homework “Results sections” must follow the example given in the
Course Content document “Writing Results of Statistical Tests in Current APA
Format” (Note: you do not have to refer to a figure). The statistical statement for a bivariate linear regression must
include at least the equation of the line and the confidence interval for the
slope (the second row under Confidence Intervals in the output).
