1. The histogram for State A is different in shape, center, and spread than the histogram for State B because the distribution of the average time spent on surfing in State A is uniform. This means that the time spent by the students of different cities in State A is very close to each other.
2. Students in State A spent more average time on surfing the internet because although there are cities in state B that spent 50 and 65 hours on the internet, they only make up a small portion of the sample.
