Question

The weights of 15 dogs are shown in the below stem-and-leaf plot. Which of the following is a false statement about the given plot?

• A. The lowest weight of the dogs is 1.1 kilograms.
• B. The data is spread from 1.1 to 4.9 kilograms.
• C. Centre of data is 2.7 kilograms.
• D. The outlier from the data is 4.9 kilograms.

Answer 1

The correct option is D The outlier from the data is 4.9 kilograms.

The given stem-and-leaf plot is


The lowest weight among all weights = 1.1 kilograms.

Hence, the first option is true.



From the graph, we observe that, the data is spread from 1.1 to 4.9 kilograms.

Hence, the second option is also true.



The data from the plot is

1.1, 1.4, 1.5, 1.8, 2.3, 2.5, 2.6, 2.7, 2.9, 3.4, 3.6, 4.1, 4.4, 4,8, 4.9

Among these data, the centre of data = 2.7 kilograms.

Hence, the third option is true.



The last option is "The outlier of the plot = 4.9 kilograms"

Here, there is no large difference between the data in the last row.

Hence, 4.9 is not an outlier.

This option gives a false statement.
