Solution Steps

Step 1: Given Values

We are given the following values:

  • \( X = 75.1 \)
  • \( \mu = 68.3 \)
  • \( \sigma = 71.8 \)
Step 2: Calculate the Z-score

The Z-score is calculated using the formula:

\[ z = \frac{X - \mu}{\sigma} \]

Substituting the given values:

\[ z = \frac{75.1 - 68.3}{71.8} \]

Calculating the numerator:

\[ 75.1 - 68.3 = 6.8 \]

Now substituting back into the Z-score formula:

\[ z = \frac{6.8}{71.8} \approx 0.0947 \]

Rounding to two decimal places, we find:

\[ z \approx 0.09 \]

Final Answer

The Z-score is \\(\boxed{0.09}\\).
