An instructor at Arizona State University asked a random sample of eight students to record their study times in a elementary statistics course. She then made a table for total hours studied over 2 weeks and test scores at the end of the 2 weeks. Here are the data: 

Study time             10            15            12            20            8              16            14            22            

Test Scores           92            75            86            76            92            80            84            81         

Assuming that a linear association exists, how are the data correlated?  Determine the exact linear relationship between study times and test scores and use it to estimate the predicted test score for a student who studies 12 hours.
