Question: The data for Exercises 1 to 4 are in the data filed named Lesson 33 Exercise File 1. Peter was interested in determining if children who hit a hobo doll more frequently would display more or less aggressive behavior on the playground. He was given permission to observe 10 boys in a nursery school classroom.

Each boy was encouraged to hit a bobo doll for 5 minutes. The timber of times each boy struck the bobo doll was recorded (bobo). Next, Peter observed the boys on the playground for an hour and recorded the number of times each boy struck a classmate (peer),

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 hobo doll. From the output, Identify the following:

1. Slope associated with the predictor
2. Additive constant for the regression equation
3. Mean number of times they struck a classmate
4. Correlation between the number of times they hit the-hobo doll and the number of times they struck a classmate
5. Standard error of estimate
