Answer 1

Answer:

The person above me is correct, and deserves brainliest.

1 )Greater than

2) Less than

Answer 2

Answers:

• Box 1:  Greater than
• Box 2: Less than

So,

• If any values in the data set are greater than the upper boundary, then those values are upper outliers.
• If any values in the data set are less than the lower boundary, then those values are lower outliers.

The general rule is that the upper boundary is found computing Q3+1.5*IQR, where IQR is the interquartile range. Recall that IQR = Q3-Q1. The Q1 and Q3 are the first and third quartiles respectively.

Another rule is that the lower boundary is found by computing Q1 - 1.5*IQR

On a box and whisker plot, outliers are points that are not connected to the main plot itself. You can think of them as islands far from the mainland.
