Question

PLEASE HELP ! MEDAL AND FAN !!

Answer 1

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.)

Answer 4

have you done the scatter plot...?

Answer 5

stop the tagging please

Answer 6

this is a question the can be done by using a spreadsheet like excel...

it will do parts 1 and 2 for you, quickly and easily...

it will probably do residuals as well.

So I' suggest you put the data into a spreadsheet, do a scatter plot by selecting it from the graph options..

it will also do line of best fit.
