Answer 3

I'm assuming, "y" is the exam mark, and "x" is the days of studying

anyhow... is mostly a calculator issue I think
if you have a TI calculator, they have regressions, linear, quadratics and a couple others

in this case, you're asked how close to a straight line it comes to
so I assume you're expected to do a linear regression, with that table of values

Answer 4

alright. thank you. I might be able to download a calculator like that online so i will see.

Answer 5

do you happen to have hmm an android phone or tablet?

Answer 6

I have an iphone

Answer 7

Maybe an app?

Answer 8

hmm rats
ok... not sure on iOS, but on android you can get Andy's graph
which is a TI calculator emulator, not sure if he's got it for iPhone, he may

anyhow, if it's available for iPhone, install Andy's graph, and then just get the ROM's online for the TIs

you can find for TI-83 plus and 84 and 86 I think or more
