Step 1 :Given that the population mean, \(\mu\), is 111, the population standard deviation, \(\sigma\), is 5, and the value, \(x\), is 100.
Step 2 :The z-score is calculated by subtracting the mean from the value and then dividing the result by the standard deviation.
Step 3 :Substitute the given values into the z-score formula: \(z = \frac{x - \mu}{\sigma}\)
Step 4 :Substitute \(\mu = 111\), \(\sigma = 5\), and \(x = 100\) into the formula: \(z = \frac{100 - 111}{5}\)
Step 5 :Simplify the expression to get the z-score: \(z = -2.2\)
Step 6 :Final Answer: The z-score associated with the value \(x=100\) is \(\boxed{-2.2}\)
