Consider the below figure attached with this question.
To find:
The conclusion that can be determined from the dot plot.
Solution:
The number of dots in the dot plot is 15. So, the number of observations is 15 and option D is correct.
The data set represented by the dot plot is:
2, 2, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 6, 6
Number of observations is 15, which is an odd number. So, the median of the data set is:
The median of the data set is 4. So, option A is incorrect.
Mean of the data set is:
The mean of the data set is 4. So, option B is incorrect.
The range of the data set is:
The range of the data set is 4. So, option C is incorrect.
Therefore, the correct option is D.
