Textbook Problem

A researcher selects a sample of *n* = 16 individuals from a normal population with a mean of μ = 40 and σ = 8. A treatment is administered to the sample and after treatment, the sample mean is *M* = 43. If the researcher uses a hypothesis test to evaluate the treatment effect, what z-score would be obtained for this sample?

To determine

**To find:** The value of *z*-score.

Explanation

**Given info:**
