Step 1

Computation of regression line equation:

Step-by-step procedure to find the regression line equation using TI-84 calculator:

• Click on STAT > Enter> Type data values of Hours/Week x under L1 and Grade y under L2.
• Enter STAT > CALC> 4: LinReg(ax+b)
• Choose XList as L1YLIST as L2.
• Select Calculate and Enter.

From the output of TI-84 calculator, the value of a is 2.977632362 and the value of b is 41.77275431.

a)

Thus, the regression equation is y =2.977632362x + 41...
