The length of time to finish a door assembly on an automobile factory assembly line is normally distributed with mean μ = 6.7 minutes and standard deviation σ = 1.2 minutes. For a door selected at random, what is the probability the assembly line time will be 5 minutes or more? Draw a sketch with the desired probability shaded and show your calculations.
