Answer: 0.60
Step-by-step explanation:
Given: Mean : ![\mu = 22\text{ minutes}](https://tex.z-dn.net/?f=%5Cmu%20%3D%2022%5Ctext%7B%20minutes%7D)
Standard deviation : ![\sigma = 8\text{ minutes}](https://tex.z-dn.net/?f=%5Csigma%20%3D%208%5Ctext%7B%20minutes%7D)
The formula to calculate z is given by :-
![z=\dfrac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
For x= 20 minutes
![z=\dfrac{22-20}{8}=0.25](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B22-20%7D%7B8%7D%3D0.25)
The P Value =![P(z](https://tex.z-dn.net/?f=P%28z%3C0.25%29%3D%200.5987063%5Capprox0.60)
Hence, the probability that a randomly selected shopper will spend less than 20 minutes in the store= 0.60
