Answer to Problem 10A
The number of cars peaks during rush hours.
Explanation of Solution
The hypothesis is a specific, testable prediction. It elaborates, in concrete terms, what a person (or chemist) expects will happen in a certain circumstance.
According to the graph, the number of cars peaks during rush hours which are at
(e)
Interpretation: A possible experiment that could test your hypothesis needs to be explained.

(e)
Answer to Problem 10A
A possible experiment that could test your hypothesis-whether the peak remains the same or not.
Explanation of Solution
Testing any supposition, principle, etc. is defined as an experiment. The hypothesis is a specific, testable prediction. It elaborates, in concrete terms, what a person (or chemist) expects will happen in a certain circumstance.After observations are completed, based on those observations, a hypothesis is created and then experiments are conducted.
A possible experiment:To see whether the peak remains the same or not, let us measure the number of cars passing through the intersection during weekdays and weekend.
