Question

I don’t have a question because I posted a photoz

Answer 1

Part a:

`Q_(1)` = 56

`Q_(2)` = 60

`Q_(3)` = 63

The quartiles are found by finding the medium of the data, and then the mediums of the two different data sets on either side of the medium. The
`Q_(2)` is the overall medium,
`Q_(1)` is the medium of the first half, and
`Q_(3)` is the medium of the second half.

-> How is the medium found? When finding the medium we put the values in order least to greatest and pick the middle value.

Part b:

The range is 7.

The interquartile range is the range of numbers between
`Q_(1)` and
`Q_(3)`. In other words, it is 50% of the data, directly in the middle.

This becomes 63 - 56 = 7

Part c:

79 is an outlier.

It is an outlier because it is 1.5 above or below (in this case, above) the interquartile range.

-> 63 + (7 +
`(7)/(2)`) ≤ 79

-> 63 + 10.5 ≤ 79

-> 73.5 ≤ 79

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.
