Answer:
The correct options are:
- Four families said they ate out twice the previous week.
- One family said they ate out 5 times the previous week.
- The median best represents the data set.
Step-by-step explanation:
We are given a data set as:
4, 2, 2, 0, 1, 6, 3, 2, 5, 1, 2, 4, 0, 1
On arranging this data set in the frequency table we get:
Number of times they went for dinner Number of families
0 2
1 3
2 4
3 1
4 2
5 1
6 1
- Hence, the range of the number line is between 0 to 6.
- Also there are 4 dots above 2.
Hence, Four families said they ate out twice the previous week.
- Also there is one dot above 5.
Hence, One family said they ate out 5 times the previous week.
- The data set is not symmetrical since the median is 2 and the data points to the left and to the right do not have symmetry.
Hence, the data set is not symmetrical.
- Also we know that the median of the data is the central tendency of the data and always best represents the data.
Hence, The median best represents the data set.
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.
Given that
The data set shown below represents the number of times some families went out for dinner the previous week.
The data set 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
Data Frequency
0 2
1 2
2 4
3 0
4 2
5 1
6 1
The data set is not symmetrical since the median is 2 and the data points to the left and to the right do not have symmetry.
From the given data set;
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)
