Pregunta 3 A statistics professor wants to use the number of hours a student studies for a statistics final exam to predict the final exam score A regression model was fit based on data collected from a class during the previous semester, with the following results: Y = 35.0 + 3X (A) What is the interpretation of the Y intercept, bo and the slope, b,? Answer: The Y intercept bo = indicates that when the student does not study for the final exam, the predicted final exam score is The slope b, = indicates that for each increase of one hour in studying time, the predicted change in the final exam In other words, the final exam score is predicted to increase by a mean of 3 points for each onehour increase score is in studying time. (B) Use the prediction line to predict the final exam score of a student that use 15 hours to study for the final exam. Answer: The predicted score is points
