An instructor at Arizona State University asked a random sample of eight students to record their study times in a beginning calculus course. She then made a table for total hours studied (x) over 2 weeks and test score (y) at the end of the 2 weeks. Here are the results. For part (g), predict the score of a student who studies for 15 hours.

a. Find the regression equation for the data points.
b. Graph the regression equation and the data points.
c. describe the apparent relationship between the two variables under consideration.
d. Interpret the slope of the regression line.
e. Identify the predictor and response variables.
f. Identify outliers and potential influential observations.
g. Predict the values of the response variable for the specified values of the predictor variable, and interpret your results.
