At a restaurant, the amount of time that customers wait for their food is normally distributed. The average wait time is 16 minutes and the standard deviation is 3 minutes. What is the z-score for a customer waiting less than 14 minutes? Round your answer to the nearest hundredth.

Step 1
The Z-score formula is given by: Z = (X - μ) / σ where: Z is the Z-score X is the value we want to find the Z-score for (in this case, 14 minutes) μ is the mean (average) wait time (16 minutes) σ is the standard deviation (3 minutes) Show more…

The time customers spent waiting to be served in a restaurant is assumed to be normally distributed with a mean of 9.5 minutes and a standard deviation of 1.65 minutes. 25 customers are randomly selected. There is only a 5% chance that the average waiting time is greater than which value? Round your answer to three decimal places. Use an online calculator.

At a local restaurant; the amount of time that customers have to wait for their food is normally distributed with mean of 24 minutes and standard deviation of 3 minutes. What is the probability that randomly selected customer will have to wait between 17 minutes and 25 minutes to the nearest thousandth?
