Answer:
B. There tended to be fewer complaints on days with more buses.
Explanation:
From the scatterplot, when the number of buses per hour increased, the number of complaints reduced.
A line of best fit drawn on the scatterplot will have a negative slope.
The diagram below illustrates a negative and positive slope on the line of best fit.
Thus, we can say that there tended to be fewer complaints on days with more buses.
The correct option is B.
