Question

The table below shows the velocity y, in miles per minute, of a toy car at different times x, in minutes:

Time (x)
(minutes)
10 20 30 40
Velocity (y)
(miles)
0.2 0.8 0.1 0.4
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 velocity of the toy car. (4 points)
[Choose the value of correlation coefficient from -1, 1, -0.04, 0.99]

Part C: Does the data in the table represent correlation or causation? Explain your answer. (3 points)

Answer 1

I think its 0.99 but I just need help with the wording for part a
for part c I know the table shows no correlation but how do I word it
