Chapter 1, Problem 10A

(a)

Interpretation Introduction

Interpretation: Timing of the highest number of cars passes through the intersection needs to be determined.

Concept introduction: Visual display of data is defined as a graph. By using the given data, a student can create graph. Graph helps to understand any data easily.

Answer to Problem 10A

Time: 8am

Explanation of Solution

According to the graph, 8am is the highest bar in the graph. So, at 8am the highest number of cars passes through the intersection.

(b)

Interpretation Introduction

Interpretation: Timing of the lowest number of cars passes through the intersection needs to be determined.

Answer to Problem 10A

Time: 12am

Explanation of Solution

According to the graph, 12am is the lowest bar in the graph. So, at 12am the lowest number of cars passes through the intersection.

(c)

Interpretation Introduction

Interpretation: The trend in numbers of cars over the course of the day needs to be explained.

Answer to Problem 10A

From 12am to 7am number of cars will slowly increase and then dramatically peaks at 8am by 5 pm .

Explanation of Solution

According to the graph, the number of cars slowly increases from 12am to 7am , then dramatically peaks at 8am by 5 pm , then slowly declines.

(d)

Interpretation Introduction

Interpretation: A hypothesis explaining the trend in numbers of cars over the course of the day needs to be explained.

Concept introduction: Visual display of data is defined as a graph. By using the given data, a student can create graph. Graph helps to understand any data easily.

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 8am and 5 pm .

(e)

Interpretation Introduction

Interpretation: A possible experiment that could test your hypothesis needs to be explained.

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.
