The function based on the input and output values is close to linear and it is decreasing (graph is attached)

<u>Answers are</u>

  • a) correlation is negative as time decreases with increase in weight.
  • b) Numeric value is obtained -0.99 by using the formula attached as picture.  It is 'very strong negative relationship'
  • c) Yes. Because weigh increase causes time to decrease
