Question

(c) a company found that employees who start work earlier do not necessarily drink more or less coffee. which statement is most likely true?
there is no correlation between start time and amount of coffee consumed.
there is a correlation between start time and amount of coffee consumed. there may or may not be causation. further studies would have to be done to determine this.
there is a correlation between start time and amount of coffee consumed. however, there is no causation. this is because there is probably an increase in the amount of coffee consumed with an earlier start time.

Explanation:

The problem states that earlier work start time does not relate to more or less coffee consumption. Correlation implies a consistent relationship (positive/negative), but no such pattern exists here, so no correlation is present.

Answer:

There is no correlation between start time and amount of coffee consumed.
