Question: The length of time to complete a door assembly on an automobile factory assembly line is normally distributed with a mean of \(\mu \) = 6.7 minutes and a standard deviation of \(\sigma \) = 2.2 minutes. For a door selected at random, what is the probability that the assembly line time will be 5 minutes or less?

Step 1 - Draw and properly label and shade the normal distribution

Step2 – Calculate the proper z score(s)

Step 3 – Find the areas needed from the z-table and complete the needed calculations with the areas Step 4 – Write a sentence in terms of the problem that contains the probability
