Final answer:
It is true that you can be fined for exceeding the speed limit in a highway work zone, as fines are generally higher in areas where there is an increased safety risk, such as where road workers are present.
Step-by-step explanation:
True, you may be fined if you are convicted of exceeding the speed limit in a highway work zone. Traffic laws are enforced to ensure safety, and in areas such as highway work zones where workers are present, fines and penalties are typically increased to promote cautious driving. When you exceed the de jure speed limit, indicated by traffic signs, you are violating traffic regulations, which can lead to fines, and in some cases enhanced penalties in designated zones such as work areas on highways.
In the provided scenarios, we see various instances where drivers are faced with decisions regarding adherence to speed limits. Whether it is driving through the intersection or responding to speed limit signs as you enter a town, it is important to comply with these limits to avoid penalties. Furthermore, if a vehicle is traveling at a constant speed on a straight road, as in scenario 33, the driver still must obey the posted speed limit to avoid receiving a ticket.
Regarding traffic violations and cell phone use, the null hypothesis mentioned in the fictional study scenario suggests that if cell phone usage and speeding violations were independent events, we would expect a certain number of people to be cited for both. However, in reality, this is something that would be statistically analyzed to understand the correlation between cell phone usage while driving and the incidence of speeding violations.
