i do have one

Have you used it before to calculate a regresstion line in the form y=ax+b?

i am a rookie at it so i have not

Have you previously used the STAT key, which brings up a menu, one of the items on which says EDIT?

yes

im there

there are numbers under L2

ok cleared

done

yes

Please move the cursor to cover MATH OR CALC.

ok done

ok done

Does it display a value for a and a value for b?

yes it does

cool. You're right up there with the best.

what is a?
what is b?

well i hit enter and it went to LinReg(ax+b) and thats it

have you pressed ENTER yet?

yes

Has the calc. responded with ifnormation / information?

oh yes it has...i had to hit enter again...it says:
y=as+b
a= .4601084431
b= 29.82726569

ab not as

yay! That was it, now its asking me the next question

Cool!

Now write down on paper that same regression equation.

thats exciting! lol

type here what the 2nd question asks you for.

ok. What is the best predicted value? Ŷ ͌ __ minutes

84

On paper, write the regression equation, subbing 84 for x. Calculate y hat.

ok got it

it says 68.551

but one more thing: It ask me to round one decimal place so that would be 69, correct?

No, that'd be 68.6. That's to 1 decimal place accuracy.

oh gotcha, ok thanks you again! Gnight!! This really helps. I feel better

Again, I'm so glad! Good night. Bye for now! Over and out.

lol bye
