WIll Award Medal!
I need help, i dont even know how i can graph this on the computer.

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.

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.

Part 2: Find the line of best fit for the data either by hand or using technology. Explain your method. Find the predicted score for each time listed in the table. 
Part 3: Find the residuals, and decide if your model is a good fit. Explain your method. (If your model is not a good fit, complete Part 2 again with a different set of points or choose a different model.)

i don't like stats
 i would start by putting the time in order by certain intervals along the x- axis
put the grades along the y- axis 
plot the grades
draw the line of best fit this is the line that goes closest to all the points
a correlation is seen if for example the graph shows that as the time spent studying increases the grade obtained is higher.|dw:1402624149910:dw|
