kirza4 [7]

Answer:

Z-score = -1.285

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 17.6 seconds

Standard Deviation, σ = 2.1 seconds

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

For x = 14.9, we have:

$z_{score} = \displaystyle\frac{14.9-17.6}{2.1} = -1.285$

A z-score to be unusual if its z-score is less than -2.00 or greater than 2.00.

Thus, the z-score is not unusual as it lies in the range [-2.00, 2.00]
