7.The paired data below consist of the test scores of 6 randomly selected students and the number of hours they studied for a test. Use a graphing calculator or software (do not calculate by hand and do not show work) to model the data with a linear function that predicts a student's score as a function of the number of hours he or she studied. Use the regression line to predict a student's score if the student studied for 7 hours.  Show your work for the prediction.
