What conclusion can be determined from the dot plot below? A. The median of the data set is 3. B. The mean of the data set is 3. C. The range of the data set is 5. D. The number of observations is 15.

Given:

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.

option 1

data plot with   3 dots over 33, 1 dot over 34, 2 dots over 35, no dot over 36, 1 dot over 37, 2 dots over 38, 4 dots over 39, and 2 dot over 40.
