(Is it possible to work this out on a ti-84? If so, how? I also want to see how its done by hand.)

Solution

Note that

Residual = actual y - y^

Here, actual y = 92.

Now,

y^ = -2.75x + 96.14

y^ = -2.75*(2) + 96.14 = 90.64

Thus,

Residual = 92 - 90.64 = 1.36 [answer]

This is also how you do it in ti-84. It has not automatic function for this.
