Question 601342: A racing car is one of many toys manufactured by Mack Corporation. The assembly times for this toy follow a normal distribution with a mean of 55 minutes and a standard deviation of 4 minutes. The company closes at 5 p.m. every day. If one worker starts to assemble a racing car at 4 p.m., what is the probability that she will not finish this job before the company closes for the day? Answer by stanbon(75887) (Show Source):

If one worker starts to assemble a racing car at 4 p.m., what is the probability that she will not finish this job before the company closes for the day?
--------------
z(60) = (60-55)/4 = 5/4
P(x > 60) = P(z > 5/4) = 0.1056
