Help please!!

Identify all of the true statements regarding the interpretation of ŷ when x = 36. The value of ŷ is
the predicted number of students that read for 36 hours.
an unreliable prediction of a language test score because the value of 36 hours is outside the scope of the model.
the language test score that any student who reads for 36 hours will obtain.
the language test score that predicts the reading time to be 36 hours.
a predicted value of the language test score if a student reads for 36 hours.
