The Lagrangian is
with partial derivatives (all set equal to 0)
for , and
Substituting each into the second sum gives
Then we get two critical points,
or
At these points we get a value of , i.e. a maximum value of
and a minimum value of
.
Answer:
(a)
Step-by-step explanation:
Given
See attachment for sets A and B
Required
The true statement about both sets
First, we calculate the typical values (mean) of set A and set B.
This is calculated as:
For A:
For B:
<em>Here, we can conclude that B has a larger typical value</em>
Next calculate the spread (range) of sets A and B
This is calculated as:
For A:
For B
<em>Here, we can conclude that A has a larger spread.</em>
<em></em>
<em>Hence, (a) is true</em>
