Practice Problems
Minimum temperature recorded = 20°C.
Difference between the maximum and minimum temperatures = 24°C - 20°C = 4°C.
The number of red balls = 10.
The number of green balls = 6.
The number of yellow balls = 6.
By comparing the above steps with the line plots, graph-1 is the appropriate line plot.
In the line plot, the numbers on the number line represent the number of chocolates eaten.
Notice that 5 students ate 1 chocolate each.
In the line plot, the numbers on the number line represent the number of burgers consumed.
Notice that 4 students consumed five burgers each.
The number line represents the numbers (1, 2, 3, 4, and 5) that are there in the data set.
The number of times each number occurs in the data set is indicated by cross marks above the respective number on the number line.
From the graph, we notice that the numbers 1, 2, 3, 4, and 5 occur 4 times, 2 times, 3 times, 6 times, and 1 time in the data set.
So, the data values in the data set are 1, 1, 1, 1, 2, 2, 3, 3, 3, 4, 4, 4, 4, 4, 4, and 5.
In a line plot, the number of times a data value occurs in the data set is indicated by cross marks above the respective data value on the number line.
The number of cross marks above 23 is 4.
So, the number of students having 23 candies in their bags is 4.
The number of cross marks above pizza is 4.
The number of cross marks above burger is 6.
The total number of students shown in the line plot = the number students having pizza in their lunch boxes + the number of students having burger in their lunch boxes.
= 4 + 6
[Substitute the values.]
= 10
[Add.]
The total number of students shown in the line plot is 10.
The number of times a data value occurs in the data set is indicated by cross marks above the respective data value on the number line.
The number of students who are 12 years old is indicated by 6 cross marks above the data value 12.
The number of students who are 13 years old = 3.
The number of students who are 14 years old = 1.
The total number of students who are at least 12 years old = the number of 12 years old students + the number of 13 years old students + the number of 14 years old students.
= 6 + 3 + 1
[Substitute the values.]
= 10
[Add.]
So, the number of students who are at least 12 years old in that class is 10.
The number of cross marks above 20 is 4, above 21 is 3, above 22 is 5, above 23 is 3 and above 24 is 2.
The number of students got scores 21 and 23 are equal.

Use the line plot to find the difference between the maximum and the minimum temperatures.
| a. | 1°C | ||
| b. | 3°C | ||
| c. | 2°C | ||
 | d. | 4°C |
Solution:
Maximum temperature recorded = 24°C.Minimum temperature recorded = 20°C.
Difference between the maximum and minimum temperatures = 24°C - 20°C = 4°C.
Correct answer : (4)

Correct answer : (2)
6.
The line plot represents a data set of numbers. List the data values of this data set.
| a. | 1, 1, 1, 1, 2, 2, 3, 3, 3, 4, 4, 4, 4, 4, 4, and 5 | |
| b. | 1, 1, 2, 2, 3, 3, 3, 4, 4, 4, 4, 4, 4, and 5 | ||
| c. | 1, 1, 1, 1, 3, 3, 3, 4, 4, 4, 4, 4, 4, and 5 | ||
| d. | 1, 1, 1, 2, 3, 3, 4, 4, 4, and 5 |
Solution:
A line plot displays data using a number line.The number line represents the numbers (1, 2, 3, 4, and 5) that are there in the data set.
The number of times each number occurs in the data set is indicated by cross marks above the respective number on the number line.
From the graph, we notice that the numbers 1, 2, 3, 4, and 5 occur 4 times, 2 times, 3 times, 6 times, and 1 time in the data set.
So, the data values in the data set are 1, 1, 1, 1, 2, 2, 3, 3, 3, 4, 4, 4, 4, 4, 4, and 5.

| a. | 6 | ||
| b. | 4 | ||
| c. | 10 | |
| d. | 9 |
Solution:
The number line represents the students age.The number of times a data value occurs in the data set is indicated by cross marks above the respective data value on the number line.
The number of students who are 12 years old is indicated by 6 cross marks above the data value 12.
The number of students who are 13 years old = 3.
The number of students who are 14 years old = 1.
The total number of students who are at least 12 years old = the number of 12 years old students + the number of 13 years old students + the number of 14 years old students.
= 6 + 3 + 1
[Substitute the values.]
