A research interested in the study habits of college freshman computed a correlation coefficient between the average number of hours a student spends watching television each day and his or her SAT verbal score. The correlation coefficient and the means and standard deviations are listed in the table below. Use this information to answer Problems 1-5.

A research interested in the study habits of college freshman computed a correlation coefficient between the average number of hours a student spends watching television each day and his or her SAT verbal score. The correlation coefficient and the means and standard deviations are listed in the table below. Use this information to answer Problems 1-5.
