Z – score = 0.5

Step-by-step explanation:

Mean delivery time, μ = 23 minutes

Standard deviation, σ= 2 minutes

Given x = 24 minutes

Now, find the z-score for the number of sandwiches delivered in less than 24 minutes.

Using the formula, $z=\frac{x-\mu}{\sigma}$

Z – score = $\frac{24-23}{2}$

⇒ Z – score = $\frac{1}{2}$

⇒ Z – score = 0.5

Therefore, 0.5 is the z-score for the number of sandwiches delivered in less than 24 minutes.
