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>
Answer:
B
Step-by-step explanation:

y = x² + 7 ( subtract 7 from both sides )
y - 7 = x² ( take the square root of both sides )
± = x
Change y back into terms of x, thus
(x) = ±
