**Mathematical Problem:**

Let \( a, b \) be positive real numbers with \( a \in \mathbb{Z} \). The set of values represented by \( i^{a-ib} \) lies on:

1. \( \bigcirc \) a ray whose argument is \( \frac{\pi}{2} \)
2. \( \bigcirc \) None of the given options is correct
3. \( \bigcirc \) a circle
4. \( \bigcirc \) a ray whose argument is \( \frac{\pi a}{2} \)
5. \( \bigcirc \) a ray whose argument is \( \frac{\pi b}{2} \)

---

In this problem, we are given two positive real numbers \( a \) and \( b \), with \( a \) specified as an integer (\( a \in \mathbb{Z} \)). We need to determine the nature of the set of values represented by the expression \( i^{a-ib} \).

**Options Analysis:**
- The first option suggests that the values lie on a ray whose argument is \( \frac{\pi}{2} \).
- The second option states that none of the given options is correct.
- The third option indicates that the values lie on a circle.
- The fourth option mentions a ray whose argument is \( \frac{\pi a}{2} \).
- The fifth option implies a ray whose argument is \( \frac{\pi b}{2} \).

To determine the correct option, one must analyze the mathematical implications of the expression \( i^{a-ib} \).

**Graphical and Diagram Explanation:**

There are no graphs or diagrams included in this problem statement. The given options are purely textual.

**Note for Students:** 
Review the principles of complex numbers and their representation to correctly analyze each provided option and determine where the set of values represented by \( i^{a-ib} \) lies.
