question 121

Short Answer

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 a graphing calculator To model the data with a linear function that predicts a student's course grade as a function of the Number of hours spent in lab.

A) y=88.6-1.86 x
B) y=1.86+88.6 x
C) y=0.930+44.3 x
D) y=44.3+0.930x
