Final answer:
The statement that is not true is that as the number of stop signs in a neighborhood increases, the average number of speeding tickets issued in the neighborhood decreases.
Step-by-step explanation:
The statement that is not true is that as the number of stop signs in a neighborhood increases, the average number of speeding tickets issued in the neighborhood decreases. The statement implies that there is a negative correlation between the number of stop signs and the number of speeding tickets, suggesting that more stop signs lead to fewer speeding tickets. However, it is possible that other factors, such as increased police presence or driver behavior, could be responsible for the decrease in issued speeding tickets.
