The leaders of the study decide to use model to make predictions about the group’s score beyond months ( year). For a given year, model is an appropriate model if the group’s predicted score at the end of the year is at least point lower than the group’s predicted score at the end of the previous year. Based on this information, for how many years is model an appropriate model? Give a reason for your answer. (Note: The end of a year occurs every months from the initial evaluation—, , )
