Answer:
The statement that supports the data is the mean distance to his friends' houses is in between 2 and 3 blocks.
Explanation:
What is mean, median and mode?
Mean: The average of the given data points.
Median: The central point of the whole data set.
Mode: The number that occurs for the maximum times in the data set.
Given:
Karl records the number of city blocks from his house to each of his friends houses.
Data set for the number of city blocks to eight friends houses:
{1, 2, 5, 3, 2, 2, 5, 3}
The first option: it is given that the maximum number of blocks the Karl lives from his friend is 4, but according to the data set, the maximum number of house blocks should be 5.
Hence, this option is incorrect.
The second option: It is given that the mode shows that Karl has 3 friends who live 3 blocks from him, but according to the given data set Karl has 3 friends who lives 2 blocks from him. Hence the mode is 2.
Hence, this option is incorrect.
The third option: It is given that the minimum distance from Karl's house to a friend's is 2 blocks, but according to the given data set the minimum distance from Karl's house to a friend's is 1 block.
Hence, this option is incorrect.
The fourth option: It is given that the mean distance to his friend's houses is in between 2 and 3 blocks.
We will find the mean for the given data set.
⇒ Mean = (Sum of all the data points) / (Total number of data points)
⇒ Mean = (1 + 2 + 5 + 3 + 2 + 2 + 5 + 3)/8
⇒ Mean = 23/8
⇒ Mean = 2.875
∴ The mean distance from Karl to his friend's houses is 2.875 which is in between 2 and 3.
Hence, this option is correct.
Therefore, the fourth option which says the mean distance between Karl and his friend's houses is in between 2 and 3 is correct.
