If you are talking about frequency in terms of waves, it is in seconds^-1
Answer:
(b) The interquartile range of B is greater than the interquartile range of A.
(d) The median of A is the same as the median of B.
Explanation:
Given


So:

Required
Select all true statements
(a) & (d) Median Comparisons


Arrange the data:




--- average of 5th and 6th

Option (d) is correct because both have a median of: 2
(b) & (c) Interquartile Range Comparisons


First, calculate the lower quartile (Q1)
[Odd n]
[Even n]


This means that:


Next, calculate the upper quartile (Q3)
[Odd n]
[Even n]

This means that:

The interquartile range is 
So, we have:


(b) is true because B has a greater IQR than A
(e) This is false because some spread measures (which include quartiles and the interquartile range) changed when the 10th data is included.
The upper quartile and the interquartile range of A and B are not equal
Answer:
C. Cloning endangered species is only a temporary solution, since a large genetic variability is needed to ensure
that an animal population will survive.
Explanation:
Also if they have identical DNA if will cause birth defects.
I believe the answer is included providing nesting cavities for breeding groups. This would increase the abundance and diversity of other bird species in the forest. Managing the forest would mean a lot more habitat for the birds to live in and procreate. This would result to an increase in birds.
