The answer is 7 R 4! hoped this helps!
<h3>Answer:</h3>
The Second one {(-8,-7), (4,-2), (2,9), (-8,8)}
<h3 /><h3>
Step-by-step explanation:</h3>
A function only gives ONE out put for a given value. But the second set has two outputs if we input -8, it gives you -7 and 8 so this must not be a function.
Based on the mean, standard deviation, and the graph, the indicated IQ score would be 115.
<h3>What is the indicated IQ score?</h3>
First, find the z value:
P(Z<z) = 1 - tail value
= 1 - 0.1587
= 0.8413
According to the z-value, this gives a value of:
z = 1
The indicated IQ score is:
= mean + z value z standard deviation
= 100 + 1 x 15
= 115
