Question 3)

Below is descriptive information for the full N = 40 adolescents on their age and delinquency (note the numbers are different from the box above).Using the information in the box below, calculate the intercept and slope of a regression equation that uses age to predict delinquency. You must include the steps you took to obtain your answer (show how you solved the equations).

Mean of Age = 13.81

Standard Deviation of Age = .98

Mean of Delinquent = 2.63
