The z-scores of the raw creativity scores 7 and 14 are -1.61 and 0.31 respectively
The given parameters are:
Mean, μ = 12.86
Standard deviation, σ = 3.65
The z-score is calculated using:
[tex]z = \frac{x - \mu}{\sigma}[/tex]
When x = 7, we have:
[tex]z = \frac{7 - 12.86}{3.65}[/tex]
Evaluate
z = -1.61
When x = 14, we have:
[tex]z = \frac{14 - 12.86}{3.65}[/tex]
Evaluate
z = 0.31
Hence, the z-scores of the raw creativity scores 7 and 14 are -1.61 and 0.31 respectively
