The table represents data collected on the time spent studying (in minutes) and the resulting test grade.
Time Spent Studying (min) 52 37 31 9 26 40 22 10 45 34 19 60
Grade on Test 95 84 72 58 77 86 72 43 90 81 62 98
• Part 1: Create a scatter plot with the predicted line of best fit drawn on it. Determine the type of correlation (if any) and predict the model that will be used.

sorry dood i wouldnt know where to start on this

undeadknight26 · Answer

Thanks anyways man.

anonymous · Answer

just plot the points on a graph aND MAKE A BEST FIT LINE ....IS That what you have to do ??

phi · Answer

finding the best fit line is a slightly complicated process.  Do you have notes on how to do it ?

undeadknight26 · Answer

A bit.

undeadknight26 · Answer

Fine the slop or any 2 dots and then...oh shoot.

phi · Answer

They may want you to use a graphing calculator.  Does that ring a bell?

phi · Answer

Or "eyeball it" which will give a "reasonable" answer see http://mathbits.com/MathBits/TISection/Statistics1/LineFit.htm
