Answer/Step-by-step Explanation:
=>Note: The data set is repeated in this question. 25 , 28 , 29 , 29 , 30 , 34 , 35 , 35 , 37 , 38, should be the data we're to find a box plot that summarises it. Options showing possible box plots are also omitted. However, we'd construct one that summarises the data.
Given the data set 25 , 28 , 29 , 29 , 30 , 34 , 35 , 35 , 37 , 38, which are ordered already, we need to derive the min, max, median, Q1 and Q3 from the given data set. These are all the values needed to construct a box plot to summarize the data.
Thus:
Min = 25;
Max = 38
Median is the middle value of the data set and it lies between the 5th and the 6th data points. The average of both values would give us our median data point = (30 + 34) ÷ 2 = 32
Our Q1 would be the middle data point of the bottom half of the data set = 29
Q3 would be middle data point of the top half of the data set = 35
(See the diagram 1 for illustration)
Having derived these values, we can now construct a box plot to summarize the given data.
(See diagram 2 for the box plot constructed that summarizes the data given).
The right box plot that summarizes the data should look like the one constructed below in the diagram attached.
