Dot plots are used to represent data using dots
The true statements about the dataset are:
- The range of the number line should be 0 to 7 to represent the frequency.
- Four families said they ate out twice the previous week.
- One family said they ate out 5 times the previous week
The dataset is given as:
4, 2, 2, 0, 1, 6, 3, 2, 5, 1, 2, 4, 0, 1
Rearrange in ascending order
0, 0, 1, 1, 2, 2, 2, 2, 4, 4, 5, 6
Represent as a frequency table
Data Frequency
0 2
1 2
2 4
3 0
4 2
5 1
6 1
See attachment for the dot plot
From the attachment, we can see that:
- 4 has a frequency of 2
- 5 has a frequency of 1
Also, the range on the dot plot can be 0 to 7, because it covers the given dataset
Hence, the true statements are: (a), (b) and (c)

Step-by-step explanation:
Dean recorded the results of spinning the spinner 60 times:
- Number 1 spun 12 times
- Number 2 spun 17 times
- Number 3 spun 15 times
- Number 4 spun 16 times
The <u>experimental probability</u> is the ratio of the number of times an event occurs to the total number of trials or times the activity is performed.
Find all experimental probabilities:
Hence, option B is correct
