Question

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

Time (x)
(minutes) 10 20 30 40
Distance (y)
(miles) 4 8 12 15

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. (4 points)

Answer 1

Choose the value of correlation coefficient from 1, 0.99, 0.5, 0.02]

Part B: What is the value of the slope of the graph of distance versus time between 10 minutes and 30 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 5

i need help for part A and C

Answer 6

i got the part b is it the slope=differences between y / differences between x
slope=8/20=2/5

@ganeshie8 please :(

Answer 13

i need help in just the part A and C

Answer 14

a. 10 = 4k, k = 2.5
20 = 8k, k = 2.5 again, so 2.5 is a valid corr-coeff.
In terms of x, it's 1/2.5 =0.4
c. The data can only represent correlation and not causation. Time cannot cause events, but events can happen at certain times.

THANKS :)

Answer 16

Beat me to it. D;

Answer 17

Distance d, time t --> the relation: d/t = 0.4 is a constant ,
The relationship is: Distance/time = v (speed).
