A researcher working with military officers would like to use the data he has collected from them to predict their health knowledge score based on this research. Would this be an appropriate application of this prediction equation? Why or why not?

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:
