Question

The table below shows the number of hours high school students of different cities of two states spend on surfing the internet each week.

State A:35,36,35,34,35,38,36,36,38
State B:24,22,20,50,25,24,65,25,26

Questions:
1.Why is the histogram for State A different in shape, center, and spread than the histogram or State B?
2.In which state did the students spend more average time on surfing the internet? Justify your answer.

Answer 1

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.
