Answer:
x = 8 ± 2i√2
Step-by-step explanation:
√-1 is imaginary number i
Step 1: Write equation
(x - 8)² = -8
Step 2: Solve for <em>x</em>
- Square root both sides: x - 8 = √-8
- Factor out negative: x - 8 = √-1 · ±√8
- Simplify: x - 8 = ±i2√2
- Add 8 to both sides: x = 8 ± 2i√2

When a finite number of samples are drawn from a larger population, the sample mean of that sample, while usually close to the population mean, is not the same thing. A population mean, on the other hand, is a description of pretty much ALL of whatever is being examined.
Example of population: Everyone in the USA
Example of a sample: One person, chosen at random, from each of the 50 states
