Textbook Problem

For each of the following populations, would a score of *X* = 50 be considered a central score (near the middle of the distribution) or an extreme score (far out in the tail of the distribution)?

**a**. μ = 45 and σ = 10

**b.** μ = 45 and σ = 2

**c.** μ = 90 and σ = 20

**d.** μ = 60 and σ = 20

**a.**
