A bus company wanted to know if the number of complaints they received was a function of the number of buses it ran. The company carried out a study comparing the average number of buses per hour for different days and the number of complaints that it received on those days. Here are the results:
||||||||
:-- | --: | --: | --: | --: | --: | --: | --: | --: | --: | --:
**Number of complaints** | $52$ | $33$ | $21$ | $23$ | $20$ | $17$ | $14$
**Avg. number of buses per hour**| $2.00$ | $2.50$ | $4.25$ | $5.00$ | $5.25$ | $6.25$ | $7.25$
**All of the scatter plots below display the data *correctly*, but which one of them displays the data *best*?**
*By convention, a good scatter plot uses a reasonable scale on both axes and puts the independent variable on the $x$-axis.*
