Final answer:
Starting March 1, 2008, New Jersey law prohibits the use of handheld cellular phones while driving, with exceptions for emergencies. Motorists are encouraged to use hands-free devices, and hypothetical data could analyze the relationship between cellphone use and speeding violations.
Step-by-step explanation:
As of March 1, 2008, motorists in NJ may not use a handheld cellular telephone while driving except for certain emergency situations. According to the World Health Organization, motorists are also advised to use hands-free devices to decrease radiation to the head, keep the mobile phone away from the body, and avoid using a cellphone without an external antenna to minimize exposure to radiation. It's important for motorists to comply with these regulations for their safety as well as that of others on the road.
For statistical analysis regarding the correlation between cellular phone use while driving and receiving speeding violations, hypothetical data might suggest that if the use of a cellphone and speeding violations were independent events, a certain number of violations would be expected among cell phone users. The provided fictional data points toward studying conditional probability or comparing expected data under a null hypothesis versus actual data.
