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.

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.

valpey · Answer

Notice that the velocity goes up and down as time goes strictly up. This tells you that the speed of the car is probably not really a function of time but rather an operator speeding up and slowing down when he/she feels like it.

valpey · Answer

We would expect that the correlation between time and velocity is very low even before we calculate it.
