A study оf the relаtiоnship between а student's test scоre on а Monday is linearly related to the number of hours a student watched television over the previous weekend. A researcher randomly selects 15 students from community colleges in the region and records both variables. She uses the LinReg feature in her calculator to get the following: n = 15, r = 0.576, y-hat = -4.067x + 93.97, y-bar = 73.25 Use the researcher's result to decide if the variables are linearly related, and then make the best prediction for a student's test score when the student watched 6 hours of television over the previous weekend.
