Answer #1

By using the TI-84 calculator we have to find the regression equation.

Click on STAT ------> Edit --------> Enter X values into L1 and Y values into L2.

Then Click on STAT --------> CALC --------> LinReg(a+bx) --------->

Xlist: L1

Ylist: L2

FreqList:

Store RegEQ:

Calculate

We get

a = - 0.3488

b = 0.8314

So the regression equation is y-hat = -0.3488 + 0.8314*x
