padilas [110]

Answer: 0.60

Step-by-step explanation:

Given: Mean : \mu = 22\text{ minutes}

Standard deviation : \sigma = 8\text{ minutes}

The formula to calculate z is given by :-

z=\dfrac{x-\mu}{\sigma}

For x= 20 minutes

z=\dfrac{22-20}{8}=0.25

The P Value =P(z

Hence, the probability that a randomly selected shopper will spend less than 20 minutes in the store= 0.60
