A.Jacob is correct. The correct value is 1 1/8 inches. All of the other data values have dots, so a data value without dots is different and is therefore an outlier.
What is an Outlier?
An outlier is an observation that lies at an abnormal distance from other values in a random sample from an Experiment.
On observing the given figure length that does not have any dots is between
[tex]1 \ and\ 1\dfrac{2}{8}[/tex]
Calculatte the value between it
[tex]\dfrac{1+1\dfrac{2}{8}}{2}\\=\dfrac{\dfrac{18}{8}}{2}\\\\=\dfrac{9}{2}\\\\=1\dfrac{1}{8}[/tex]
Hence Jacob is correct. All of the other data values have dots, so a data value without dots is different and is therefore an outlier.
