Answer 1

What is the daily average number of trucks parked at the lot that week?

Answer: From the scatter plot, we can see the number of trucks at the parking lot each day for a week. The numbers are:

2, 2, 3, 3, 3, 4, 5

Therefore, the daily average number of trucks parked at the lot that week is:

$Average=\frac{2+2+3+3+3+4+5}{7}$

                    $=\frac{22}{7}$

                    $=3.1$ rounded to nearest tenth.
