Question

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

Answer 1

A] The most likely value of the correlation function for the data is -0.04, this i because the relationship between the two variables time and velocity do not how a strong linear relationship between them.

Part B:
The value of the slope between times 10 min and 20 min will be:
slope, m=(y-y1)/(x-x1)
thus taking points (10,0.2) and (20,0.8)
slope,m=(0.8-0.2)/(20-10)=0.6/10=0.06 miles/ min²

c] The relationship will be described as causation/ causality because time is partly responsible for the velocity of the toy and velocity is partly dependent on time.
