Answer:
This example is not a random example due to the fact that it is only questioning the eighth-graders. Random sample means that the sample is chosen simply randomly and everyone has an equal opportunity to be apart of the sampling.
Step-by-step explanation:
X = 3 + bi
|x| = √(3² + b²)
|x| = √(9 + b²) ..............(a)
But from the question |x|² = 13
|x| = √13
Substitute this into equation (a)
|x| = √(9 + b²) ..............(a)
√13 = √(9 + b²)
13 = 9 + b²
9 + b² = 13
b² = 13 - 9
b² = 4
b = √4
b = + or - 2
Possible value of b is +2 or - 2.
