The upper quartile is shown incorrectly in the box plot. So, the third option is correct.
Given
Data values are: 93, 83, 74, 74, 83, 92, 93, 94, 90, 87, 83, 86.
Box plot has a minimum value equal to 74, lower quartile equal to 83, median equal to 86.5, upper quartile equal to 89, and a maximum value equal to 94.
What is the upper and lower quartile?
The upper quartile is the value of the middle of the second set, where 75% of the values are smaller than Q3 and 25% are larger.
Arrange the data values in ascending order.
74, 74, 83, 83, 83, 86, 87, 90, 92, 93, 93, 94
Divide the data in 4 equal parts.
(74, 74, 83), (83, 83, 86), (87, 90, 92), (93, 93, 94)
Then,
The maximum value is 74.
The value of the first quartile is;
[tex]=\dfrac{83+83}{2}\\\\ = \dfrac{166}{2}\\\\=83[/tex]
The value of the third quartile is;
[tex]=\dfrac{92+93}{2}\\\\=\dfrac{185}{2}\\\\=92.5[/tex]
And the value of median the given data is;
[tex]= \dfrac{86+87}{2}\\\\= \dfrac{173}{2}\\\\=86.5[/tex]
Hence, the value of the upper quartile in the box plot is 89 which is not equal to 92.5. Thus, the third option is correct.
