The table shows the age and finish time of ten runners in a half marathon.
tiny-mole [99]

Answer:

Left box: Outlier in this data set is (57,132)

Right box: because the finish time looks faster than expected for the age.

Step-by-step explanation:

As per the given table shows the age and finish \ time of 10 runners.

It is clear that people of age around 35 are finishing at around 142 \ minutes

and person with older age takes longer to finish.

One person of age 57 finishes in 175 \ minutes , that looks as expected.

Another person of same age (57) finishes it too fast which is unexpected.

Therefore (57,132) is an outlier, because it looks a faster finish as per expected.
