Question

Somebody help please, thanks!

Question 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.

Answer 1

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

why did you repost the same question? Please don't mass-tag. Again, I am not the best stats person.

Answer 5

@triciaal No one from the previous question was online, which meant that any new person would have to re-read EVERYTHING. Alsdo, we didn't get that far in the first place, and it was too clustered.

Answer 6

Where is your scatter plot? Please draw it in the Draw utility and share it with the rest of us.

Draw in the best fit line (by eye).

Determine whether or not the correlation coefficient exists, and, if so, calculate it.

Find the equation used to calculate the correlation coeff. and share it here, so that others can give you feedback on your work.

Answer 7

i'm actually pretty good with stats, lol.

Answer 8

@mathmale I can bring the drawings that Zela made yesterday

Answer 9

No, I want YOURS, not Zela's.

Why are you tagging so many people? I'd be more sympathetic had you shown some work of your own up front, but you seem to want others to guide you through this whole problem from scratch. Self-reliance is extremely important.
