Using this model, if a 15-year-old scored 70 on his academic knowledge exam, what would you expect him to score on his health knowledge exam?

Assume that age and academic knowledge (graded exam: 0–100%) have been shown to be related to health knowledge (knowledge questionnaire score: 0–100%) among teens. A nurse researcher would like to use the data she has collected from a random sample of 118 teens living in urban centers of New York to predict their health knowledge. She enters the data she has from their academic knowledge test and their ages into SPSS and formulates the following tables from the multiple regression option:
