Sammy's Sandwich Shop has a mean delivery time of 25 minutes with a standard deviation of 2 minutes. Determine the z-score for t

fiasKO [112]

Answer:

-1

Step-by-step explanation:

Given: Mean= 25 minutes.

Standard deviation= 2 minutes

x= 23 minutes.

Lets find the z-score for the number of sandwiches delivered in less than 23 mins.

Formula: Z-score= $\frac{x-mean}{standard\ deviation}$

Z-score= $\frac{23-25}{2}$

⇒ Z-score= $\frac{-2}{2}$

∴ Z-score will be -1

Hence, -1 is the z-score for the number of sandwiches delivered in less than 23 minutes.
