Question
Determine whether the scatter plot of the data for the following situation would have a positive or negative linear association -Time working and amount of money earned .
Hint:
A positive association happens when the slope of the linear trend line is positive. If the slope is negative, it describes a negative association.
We are asked to find whether, ‘Time working and amount of money earned’ has a positive or negative linear association.
The correct answer is: We are asked to find whether, ‘Time working and amount of money earned’ has a positive or negative linear association.
ANSWER:
Step 1 of 1:
We know that, there is a fixed pay for our daily tasks. If we work for extra hours, we are bound to receive an extra pay for the hours worked.
That is, when we work overtime, we are get paid more. This is a direct relation. Hours worked and the amounts of money earned are directly proportional. Hence, the slope of the relation would be positive.
Thus, there exists a positive association.
Data that are directly proportional to each other has a positive slope.
