Question

Help pleasseee??? It's been like over an hour...

Answer 1

The table below shows the distance y, in miles, traveled by a toy car in x minutes:

Time (x)
(minutes) 20 30 40 50
Distance (y)
(miles) 5 10 15 20

Part A: What is the most likely value of the correlation coefficient of the data in the table? Based on the correlation coefficient, describe the relationship between time and distance traveled by the toy car.
[Choose the value of correlation coefficient from 1, 0.8, 0.5, 0.02]

Part B: What is the value of the slope of the graph of distance versus time, and what does the slope represent

Part C: Does the data in the table represent correlation or causation? Explain your answer.

Answer 2

All the points are EXACTLY on the straight line - what does that tell oyu about the correlation?

slope of the graph is (change in y)/(change in x)
In this case it is the distance covered/time taken to cover it

What is another common term for miles/minute (or miles per hour, or miles per year....)?
