To answer the question, we need to analyze the dot plot shown in the illustration. A dot plot is a visual representation of data, where each dot represents one observation.
Based on the dot plot, we need to determine which statement is true.
Looking at the dot plot, we can see that there are X's marked over each number from 2 to 5 on the number line. This suggests that there were observations made for each of these numbers.
Counting the number of X's, we can see that there are four X's marked over the number 4, indicating that there were four observations of people playing video games for 4 hours.
Therefore, the statement "Four of Nakeysha’s friends are observed" is true based on the dot plot.
In summary, based on the dot plot, the correct statement is that four of Nakeysha’s friends are observed.
There will be 11 dots above the number 47 in the dot plot.
There will be 5 numbers in the dataset that will be in the bin that goes from 62 to 64.
Based on the given information, the correct statement is:
Four of Nakeysha’s friends are observed.
