Question

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 B: What is the value of the slope of the graph of velocity versus time between 10 minutes and 20 minutes, and what does the slope represent? (3 points)

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

Answer 1

i have part C is 0 correlation but im stuck on part A and B

Answer 2

i need help on part B only

Answer 3

@amistre64

Answer 4

what does the slope between 2 points represent? what are your thoughts?

Answer 5

time?

Answer 6

i was thinking more of an average of something ...

Answer 7

oh like 15?

Answer 8

sorry im really confused

Answer 9

the slope between 2 points provides us with an average rate of change.

in this case, its the average rate of change with respect to velocity

Answer 10

so it represent the velocity??

Answer 11

the rate of change in velocity is defined as acceleration.

Answer 12

m/s
---- = m/s^2
s

Answer 13

but that is a physics thing, not sure how it applies to statistics tho

Answer 14

so the answer would be the acceleration?

Answer 15

the average acceleration ... would be my best guess. if its correct or not i would not know.

Answer 16

thank you so much

Answer 17

good luck
