A 14-year-old patient reports to the emergency room following a cycling accident where he fell off his bike and struck a tree with his arm.  X-rays show that this patient has a fractured humerus. The patient presents with significant weakness with elbow and wrist extension.

A study of the relationship between a student’s test score on a 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.
