Solve the problem using your calculator.A study was conducted to compare the average time spent in the lab each week versus course grade for computer students. The results are recorded in the table below. Use linear regression to find a linear function that predicts a student's course grade as a function of the number of hours spent in lab. Number of hours spent in lab Grade (percent) 10 96 11 51 16 62 9 58 7 89 15 81 16 46 10 51
A. y = 1.86 + 88.6x B. y = 0.930 + 44.3x C. y = 44.3 + 0.930x D. y = 88.6 - 1.86x
