Kaylis [27]

Answer:

B) There is a correlation between start time and amount of tea consumed. There may or may not be causation. Further studies would have to be done  to determine this.

The extent to which the two components or data are related to each other is highlighted with correlation. The change in one component brings the same amount of change in the other component. Correlation discloses the way the variables are related.

3*2 - 1
